Help with ACF 4/6/20
Hello, I've had my from for 7 years. About 2 years ago he got soft
He was still happy, eating and singing. I recently changed his diet bc I
was told the wrong thing at Petco, and he got better for a few weeks.
Now he developed this on his under belly and I just noticed the hole
Any recommendations? Thank you
<Bloating in Xenopus is not uncommon. Your specimens are a reasonable
age, given they can live 20+ years, indicating essentially good care,
but it's always worth reviewing living conditions. Do start reading
Always a good website for sick Xenopus. Maracyn II is minocycline, while
Maracyn Plus is trimethoprim and sulphonamide. The RSPCA suggest
Oxytetracycline for bacterial infections, so that's another alternative.
If you haven't already read their report (aimed at vets and lab workers,
useful for us pet-owners too) have a read:
Both sources recommend the use of salt, which through osmosis will draw
out some of the water. A good starting point would be 2 gram/litre, but
Xenopus are surprisingly salt-tolerant amphibians, and you could raise
this a bit after a week or so to perhaps 3-5 gram/litre for a few days
if needs be.
After a few days, come back down to 2 gram/litre. What you should find
is the swelling goes down. Hope this helps, Neale.>

Question about my albino African clawed frog
Could use some help. Included is a picture of my albino African clawed frog. As
you can see it has a “blister” coming from it’s back end. It has been like this
for the past 2 days.
<Medicate quickly; you have limited time here! Bacterial infections rarely fix
themselves, and these frogs quickly sicken and die. I'm going to send you to
some reading, here:
If you look at the Red Leg section, you'll see what you're dealing with, and the
recommendation to try Maracyn II and Maracyn Plus. If antibiotics aren't
available without prescription where you live, a vet may provide them if asked,
or else you'll have to resort to a reliable antibacterial such as eSHa 2000.>
It is in a tank with one other frog who doesn’t have any issues.
<Yet! I'm a bit concerned by the substrate, which is much too coarse for these
frogs, and could easily explain the damage. Standard operating procedure for
these frogs is to use NO substrate at all, but alternatively, a very smooth,
lime-free sand (such as smooth silica sand or pool filter sand) can be used.
Avoid gravel because they can swallow it and that usually proves fatal if not
I have had them for 6 months now. I have tried google searching for possible
diseases or fungus. Nothing appears to match my frogs symptoms. If you can
please let me know what you think this could be and a possible solution to help
Thank you for your time,
<Hope this helps! Cheers, Neale.>
Re: Question about my albino African clawed frog
Thank you for getting back to me. I am going to change the gravel & try to find
the antibiotics today.
<Glad to help and good luck! Neale.>
Eggy ADF with red scratch under mouth.
This is my first time writing in but I have spent MANY hours on here reading up
on ADF care. There is so much to learn.
Established/Cycled 10 gallon tank with Aqueon HOB filter-upgraded to sponge &
bio-ceramic rings and a sponge over intake filter, heater maintaining 78-80° and
an air stone. Substrate is tumbled/smooth med-sized gravel, a driftwood log, a
tall silk plant, 5 moss balls, a terra cotta pot for hiding and dish for
<Sounds great, though I might nudge the heater down a bit; 25 C/77 F is fine.>
Inhabitants: currently 1 male and 1 female ADF, and 2 Nerite snails
(I lost 2 ADFs to bloat and 1 to Red Leg disease about a week ago)... Since
then, I got some Koizyme to add to the tank at 4 drops/week in order to help
help snuff out gram neg bacteria, responsible for Red Leg, but my understanding
is that I need to increase my alkalinity to around 100 ppm for it to work
<Possibly. But Koizyme is a supplement for use with Koi carp, and absolutely NOT
an antibiotic. I'd no more rely on this product to cure a disease than something
like Melafix. What you want is a proper antibiotic, such as Kanaplex, or failing
that, a reliable antibacterial medication such as eSHa 2000.>
So, today I started adding 1/2 tsp baking soda and plan to do this daily for 3
or 4 more days to avoid sudden changes that ADFs don't like. Is this okay?
<See above. What you're doing is not going to do any harm, but it's not a
reliable fix either. Your frog might well get better under its own steam, and
the Koizyme product will help create good conditions, though I don't really
understand why you've selected a pond treatment for a tiny fish tank. Isn't
dosing really difficult? The bottle seems to indicate teaspoon per 500 gallon
PH-6.8 (hoping b.soda will help this move to more alkaline… > 7.0 )
<It will, but around neutral, 6.5-7.5, is fine for these frogs.>
I thought the other 2 adf's might also get bloat, decided to wait a bit before
replacing any, and sure enough 2 days ago the female started getting bigger, but
now-instead, I believe she is eggy because she looks much different than the
others who got dropsy. She is not puffed up all over-- just her belly.
<Could easily be gravid, yes.>
But I confirmed today with a good picture that she has a red sore/wound? on the
underside of her mouth. Should I go ahead and treat the water with something?
<I would always, ALWAYS treat wounds on frogs as per Red Leg, simply because
healing sick frogs is extremely difficult. Best to use the medication as soon as
wounds appear, rather than once those wounds becoming infected.>
(I don't have a hospital tank).
<Not an issue here. Antibiotics won't harm the other frogs or snails.>
Side note: I discovered that VitaChem can go a long way helping beta fish grow
back their tails and is ultimately a great product for any and all fresh water
fish…boosting their vitality. I should have some by tomorrow.
<None of these "boost" products is worth investing in. It's kind of like your
doctor's opinion of vitamin pills -- for most healthy people eating balanced
diets, vitamin pills contribute absolutely nothing of value whatsoever. Likewise
here, anything marketed as a "boost" is more about extracting money from anxious
fishkeepers. As/when fish or frogs get sick, you need to treat the pathogens
involved with reliable medications, not vitamin supplements or whatever. You
want an antibiotic here. Here in my country, the UK, antibiotics are only
available from a vet, so for small fish and frogs, it's simply doesn't make much
financial sense to visit a vet, so we tend to use antibacterial medications like
Protozin or eSHa 2000 that work almost as well. But as I say, anything marketed
in vague terms as a "boost" or "supplement" or "tonic" is probably a waste of
Would this help my, frogs too?
<Almost certainly not. Your frog might get better of course, but the VitaChem
likely won't have been the key factor in its recovery. Cheers, Neale.>
African clawed frog bloat 4/13/17
Your site is without a doubt the most informative on various
Neale emailed me the other day but I have another question. We have an
African clawed frog with soft bloat and am working hard to save/help
We have been doing the Epsom salt soaks. I just received the product
Maracyn II today and need to find the right dose. I'm going to treat him
in hospital tank. Can the dose be adjusted with the same effectiveness
in 1 gallon of water?
If so what would the dose be? The Maracyn II is in powder form.
Recommended dose is 2 packets in 10 gallons of water.
<2/10 = 0.2; i.e., one-fifth of a packet per 1 US gallon.>
If effectiveness will be compromised I will use 10 gallons of water.
<Realistically, once you open the packet of medicine, oxygen gets in,
and the antibiotic won't stay "good" for long. So unless you plan on
using up the rest of the Maracyn within the next few weeks, I wouldn't
much. If I recall, you dose once, then a couple days later, dose a
second time. That being the case, I'd save one packet of Maracyn II
somewhere cool and dry, and only open one. Put half of that into 5
gallons of water, stir
well, remove the old water from the aquarium, and put this new,
medicated (and dechlorinated) water for the tank. Roll up the packet
tightly, store inside an airtight bag or container, and store carefully
away from moisture
and bright light. Then when the second dose comes around, I'd use the
other half of the packet in a new 5 gallon container of water,
dechlorinate, and then use as before. Make sense?>
As well, do I still soak Michael in the Epsom salt the same day as I do
the Maracyn II treatment? (of course in 2 separate treatments)
<Yes, you can use Maracyn II alongside Epsom salt.>
Re: African clawed frog bloat (RMF, feel free to edit out the drugs
ref.)<Mmm; I'd leave. B> 4/13/17
Thanks again for your quick response.
I'm a bit dumb with math.
Do I split the powder dose (one packet) into 5 doses, then add one of
those doses to a 1 gallon tub of dechlorinated water, in which I would
put Michael in?
<It's 2 packets in 10 gallons, correct? If so, then 1 packet in 5
Or one-fifth of a packet in 1 gallon. The problem is really dividing a
small packet of white powder into 5 equal portions -- perhaps find your
friendly neighbourhood coke dealer to help with this bit!>
I am trying to treat him out of the tank in a separate bucket. As well,
how long would I soak Michael?
<Follow the instructions on the packaging, but normally Maracyn 2 is
added to an aquarium and left like that for at least 24 hours.
Antibiotics are very poorly absorbed through the skin and mouth this
way, so it takes a long time for the fish or amphibian to get enough
antibiotic inside them to get better. So if your vivarium contains 1
gallon of water, then just add the Maracyn 2 to that water and leave it
P.S. We got him to eat fresh chunks of salmon! I have read salmon is
good for them. Do you know if salmon can be a regular diet?
<Certainly once a week should be no problem at all; indeed, being oily
it contains a lot of fat-soluble vitamins absent from other foods.
HOWEVER, oily fish is messy, so I tend to use it just before doing a
water change. I
would not use oily fish as a staple though. It isn't really an
appropriate food for frogs, especially when there are other, more
balanced food items out there, such as earthworms.>
Many thanks again,
Seeking ACF Medical Advice
Hello, one of our ACFs died yesterday (only 5 years old), presumably due
to an ammonia spike or bacteria due to a weakened immune system. The
tank has had issues with ammonia over the past two
months and the frogs we
excessively shedding. We became concerned about his health two weeks ago
when he refused to eat. Typically, we feed the frogs ReptoMin pellets
but decided to try red wrigglers last week to see if he would eat. He
decently size worms and satisfied us that his appetite had returned
(he's always been a light eater). five days later we found him floating
around the top of the tank, we were unable to see bloating and when
approached, he swam back to the bottom of the tank before swimming back
to the top to float about fifteen seconds later. The next morning we
found him floating dead in the tank. Ammonia was a little over 2 ppm.
Immediately I removed the deceased frog and took several pictures (Link:
http://imgur.com/a/rTL8b) and proceeded to clean out the entire tank
along with all decor. The other three frogs were returned to the tank,
all gravel at the bottom was removed to prevent future trapping of waste
and I started them on a round of tetracycline to be safe. Wanted to get
a second opinion and ask how long to wait to place the biological media
back into the filter after the carbon has been reintroduced to clear out
the remaining tetracycline four days from now.
<I agree that this does look like a systemic bacterial infection
following exposure to some environmental stress, but without doing
detailed microscopy, it's hard to be sure. I think your approach of
cleaning out the tank, doing water changes, and treating with an
antibiotic is a good one.
Antibiotics generally lose their effectiveness within 24 hours in the
warm, oxygenated environmental of an aquarium, so I wouldn't worry about
waiting too long between the last dosage and removing the carbon. It's
not as if residual tetracycline will cause any problems. Let me also
stress the importance of doing the complete course of tetracycline as
recommended by the manufacturer or your vet. Incomplete courses of
antibiotic are the major factor behind antibiotic resistance, and we all
have to play a part in staving off this particular doomsday scenario!
Re: Seeking ACF Medical Advice 4/19/17
Hello Neale, finished the full course of tetracycline and two of the
frogs are back to eating.
<A very good sign.>
The female, age five, however, has been shedding profusely and refuses
to eat regardless of the food since the other frog died.
<Less good, but probably not a huge amount you can do at this point.
Give it a week, keep up with water changes, and see what happens. If her
condition worsens, for example she is obviously losing weight, then a
second full course of antibiotics might be helpful. But do also try
offering a range of foods, for example earthworms, even if she's off her
Water conditions: Nitrates 20 ppm, Nitrites 0 ppm, ammonia 1 ppm.
Current course of action we're thinking is to continue water changes
every 1-2 days (dependent upon water conditions) to control ammonia
levels between weekly feedings, though we're certainly open to
<What you're doing seems fine. The ammonia is a problem though, and may
well be causing the shedding -- so using an ammonia remover, such as
Zeolite, in the filter could be very helpful. Certainly,
filtration (e.g., by adding an extra filter, or simply increasing
flow-rate through the existing filter) ensuring biological media is of
the best possible quality/type. Xenopus aren't especially ammonia
sensitive in the
short term, but 1 ppm is quite a high amount by any standards; I would
not be feeding at all like this, and probably wouldn't feed until
We also have a second full course of tetracycline on hand if you think
it may help.
<Good luck! Neale.>
My Albino frog (condition not mentioned)
hi, i have had my albino frog for quite some time buying it when it was hardly
any bigger than a Congo frog, It has grown within a Large Community Tank 320L
(im from UK so don't use Gallons) and now is what i expect Full Size taking up
the most of palm of hand However within the past week i have noticed -kind of
hard not to.
That One of its eyes has became Swollen and Red, As if
it had gotten some sort of Black eye, however at first thought i thought perhaps
it had a run in with one of my Catfish, but as the days passed its mouth seemed
to be forced Open and i see a large Red ~Something~ Only be described as some
sort of Growth and it shows no signs of Stopping and only getting Worse, The Red
Growth is only on one side of the mouth and Seems to be under the Eye as well.
Looks like it might be a clump of Red Flesh but i fear it could be a tumor and a
Death Sentence to the frog. i don't really have another Aquarium set up suitable
for the frog without Risking others or himself being Eaten. If there is anything
i can do to Improve his/her Condition i would greatly like to know as i can find
little on the internet.
If worse turns to worst and indeed there is nothing i can do, Perhaps there is
something i can do to make its Last days as comfortable as possible.
It might be worth a note to mention that all my Fish both Scaled and those
without scales are Healthy and fine, Water Conditions are also more than
Satisfactory and there is no Problems with other Tankmates.....Plus there is
nothing missing from my tank so he hasn't Eaten someone bigger than he can chew.
i Greatly look forward to hearing back Your Opinions and Feedback, Thanks for
listening (Reading).....Lee H.
<Hello Lee. The short answer is that medicating aquatic frogs is somewhat
difficult, and the best/most reliable approach is to use antibiotics. A vet will
be the easiest source of these, which is awkward I know, but in the UK, the only
legal way to obtain antibiotics. Your frog would appear to have an opportunistic
bacterial infection, often referred to as Red Leg.
This is invariably fatal unless promptly treated with antibiotics such as
tetracycline. A vet will provide you with details on dosing, etc. Expect to pay
around £15-30 for treatment, which may include injections (the best way to
deliver drugs) rather than stuff you add to the water (a pretty hopeless method
in serious cases). The RSPCA and PDSA may also be able to help, and speaking
with people in your local reptile pet club or store may provide some tips on
vets able to provide useful support. To be clear: there are NO reliable
off-the-shelf medications sold in pet stores, which is why prevention of disease
in amphibians is so important. Mixing frogs with fish invariably goes wrong
eventually, and while it's hard to say what the immediate cause of your problems
was, damage by a catfish or some other spiny aquarium resident is one
possibility, even when the frogs aren't kept with predatory or aggressive
fishes. Cheers, Neale.>
help needed with African frog
I have two African Clawed Frogs in a 40 litre
aquarium. They were doing very well and cohabitated
peacefully with the other inhabitants of the tank. Recently I
noticed that one of the frogs was suffering from a swollen leg.
The swelling is in the "ankle" area just before the
webbed feet. The webbing seems okay but the affected area has
become dark black.
The frog is not moving much, preferring to hover near the surface of
the water and seems to have difficulty in moving that particular
leg. He is eating normally, but not moving much. The temperature
of the water is 78 degree Fahrenheit and I carry out water changes
regularly. The other frog seems to be in good health. Can
you give me some advice as to how to treat this problem? Thank
you very much.
<Hello Donald. Do have a read of this page, here:
Redness and swelling of the limbs is dangerous, and difficult to treat
without antibiotics. It's a bacterial infection, but triggered by
environmental conditions, so review and act accordingly.

African Claw Frog tumour?
My two year old albino ACF has suddenly developed a lump under the skin
at the top of his leg, just down and across from his bottom.
He appears to be his normal self, feeding and swimming without any
difficulty and the lump doesn't appear to have changed at all in
the last couple of days and he is not bloated or discoloured in any
way. I feed him
every other day on a mixed diet of frozen thawed red/white mosquito
larvae, Artemia, daphnia etc, live mini meal worms and dried fish
<Sounds a good variety of foods.>
Is this likely to be a tumour or some sort of bowel blockage?
<If the swelling is in the limbs, then yes, a tumour of some sort,
benign or otherwise, is likely. Abdominal swelling caused by
constipation is usually very obviously such, and constipated animals
tend not to want to
eat much. The use of Epsom salt and live daphnia or live brine shrimp
will usually shift constipation. But tumours are virtually impossible
Fortunately, they're quite rare, and if they don't obstruct a
sense organ or orifice, shouldn't cause the frog any undue harm.
With luck, the tumour may subside in time. In the meantime, do review
basic living conditions, in particular things likely to promote tumour
formation -- water quality, lack of vitamins, chlorine in the tap
water, use of copper, etc.>
Many thanks in anticipation for your advice.
<Hope this helps, Neale.>
Re: African Claw Frog tumour? 6/13/2011
Many thanks for your reply Neale, it is very much appreciated. Since
posting my message, my frog has allowed me a better opportunity to get
a really good look close up at the lump and it is in fact where I can
best describe as directly over his right bum cheek (were he to have
one!) I can say with some certainty that it is not in his leg. His
stomach and the rest of his body is not bloated and I have watched him
eat both the frozen food and the live with his usual vigour in the last
few days but the lump has not passed nor changed in size/shape.
My husband is firmly in charge of keeping the tank in tip top condition
and I am confident this is all at the correct level. It really is
baffling and I feel rather helpless and very worried about my little

If you Google terms such as "tumour" with "Xenopus"
you'll see that such things are commonly investigated in
laboratories, Xenopus laevis being one of the classic lab animals.
Tumours may be genetic, but they can also be caused by exposure to
heavy metals (for example copper) and various other chemicals that are
toxic rather than immediately fatal. Vets can remove tumours depending
on where they're located on the animal, and when performed
properly, the frog can go on to enjoy a long and happy life.

African clawed frog swimming strangely and discolored
My son has a ACF that seems to be taking a turn.
It has been healthy and fine, to this point, but I did notice it was
turning a darker green color in blotches, rather than staying it's
pretty light green color.

I am not sure how the Pet Stores stay in biz. ugh
<I look at it this way: A sales clerk wouldn't stop himself
selling me a ghastly pair of yellow trousers with pink polka dots.
<<Hey! I bought those!! Heeee! RMF>>
It's up to me to make an appropriate choice. So with a pet shop:
They'll sell any animal to
anyone who pays the money, regardless of the ability of that person to
keep that animal. Yes, I agree, the *ethics* is totally different,
since it's an animal we're talking about, an animal that can
suffer in various ways. But so long as the law doesn't enforce some
sort of ethical dimension, it's up to us to make sure we research
the needs of those animals prior to purchasing them. I do my best to

Two ACF's with red sores 4/28/09
Hello, my question is concerning my two African clawed frogs. One is a
male who is 4 or 5 years old, the other a female who is about 3 years
old. They live in a 20 gallon long tank. They have Whisper internal
filter 20 to 30 gallons, a heater and a cave. No bottom substrate at
<All sounds good.>
Apart from my male getting something that made him shed three times a
day last year, which was easily cleared up, neither has been sick until
know. About 4 weeks ago I noticed the female had a red eye and lip and
was swimming incredibly crooked. She still had quite an appetite. So I
treated the tank with salt and
Fungus Clear, which is what the guy at my local pet store said would
<Salt is sometimes used with Xenopus to reduce swelling, and
sometimes alongside the appropriate medications. But in this instance,
it doesn't sound as if your frogs have fungus. Fungal infections
are very distinctive: white, fluffy patches on the body. The standard
treatment is Mardel MarOxy.
For bacterial infections -- what I suspect your frogs are dealing with
-- either Maracyn II or Maracyn Plus are recommended.>
He also said to treat them both as the male would likely get it too.
After two weeks of treating, water changes and the female going crazy
and jumping out when I opened the lid, she seemed to be better. (I
learned to not open the lid unless she was in her cave). No more red
anywhere on her body, but she still wasn't swimming too great. So I
continued the treatment for 3 more days. her swimming wasn't
getting any better, nor was it getting any worse. She was still eating
fine. All levels of ammonia, nitrite, nitrate, PH were good.
<Meaning 0 ammonia, 0 nitrite, and a steady pH between 7.5 and 8?
Xenopus do need hard, alkaline water to do well.>
None of them spiked during treatment. Everything was fine an dandy for
a few days when I noticed the male had a red sore about the size of my
pinky nail in the center of his belly. His front toes are reddish, but
not too bad and the tip of his snout is red. The rest of his belly is
perfectly creamy white, as are his legs. He is
swimming fine and eating fine
<It does sound like a bacterial infection, something like Red Leg.
This is an opportunistic bacterial infection caused by Aeromonas,
equivalent to Finrot in fish.>
I started the treatment again last night. 1 tablespoons of aquarium
salt per 3 gallons of water, 2 tablets Fungus Clear and a water change
every 3 days. No carbon in the filter so I'm not feeding them as
much because I don't want the ammonia to spike. There is no ammonia
as of midnight last night. PH, Nitrite, Nitrate and all that good stuff
is perfect. I have been treating them again for 3 days and the male
doesn't seem to be getting any better. Not worse and it isn't
spreading, but not better.
<Well, the fungus medication isn't helping and you should be
using an anti-bacterial treatment instead.>
Do you have any suggestions at all that could possibly help? The
treatment only seems to be keeping the infections at bay, not getting
rid of them.
Any other medications I could try?
<Weirdly, I'd just finished writing a whole piece about aquatic
frogs for WWM, so if you stop back in the next day or two, you should
see something come up on the New Articles page, here:
In the meantime, treat with antibacterial medications as explained, and
as with Finrot, review possible triggering factors: water quality,
physical damage, rough handling. Cheers, Neale.>
Re: Two ACF's with red sores 06/03/09
Thank you for your quick reply. I don't know what was up with
the male, but before I got to treat him he shed his skin and the
sore was gone.
<It is often the case that healthy animals get better of their
own accord; at least some of the time, optimal water quality and
diet are the key things, and medication helps more in preventing
infection, rather than fixing whatever is immediately and
But darn it the female did not get better. Her eye cleared up and
the redness on her lip lessened, but her other eye went cloudy
and she developed a sore on the other side of her lip. She lost
her appetite and
hasn't eaten in three weeks. I treated her with Maracyn TC
everyday for two weeks, but she didn't get any better. I
isolated her this morning in her own ten gallon with a filter. I
noticed her legs were twitching. This only lasted a few seconds
immediately after I put her in the tank and then she stopped and
hasn't done it since. I noticed she has had a little trouble
reaching the surface.
<Do lower the water so she can "stand" up if needs
Her legs look fine. I have attached some pictures of her. She
doesn't appear to be in pain, but since she is a frog I guess
it is kind of hard to tell if she is or not.

different antibiotic if Maracyn TC (which is a Tetracycline) to

to try to get some antibiotics down her throat if it would help

Re: Euthanizing Xenopus, now salt form. with
frogs 2/15/09 Dr. Monks, I wonder if I can
ask an unrelated follow up? In my 55g frog tank I have two Apple Snails
that are showing REALLY poor shell growth. You once recommended a
Malawi Salt mix recipe for some snails I had in another tank. Can I use
this in the frog tank, or will it hurt them? Thanks again. Laura <Hi
Laura. Used as indicated, Malawi Salt mix will do snails no harm at
all. It is important that the carbonate hardness is reasonably high
when keeping Apple Snails otherwise, as you've probably observed,
they develop thin, brittle, discoloured shells with lots of pitting.
Re: Euthanizing Xenopus 2/16/08 Thank you. Um
I wasn't worried about it hurting the snails, sir. I was wondering
if it would hurt their Xenopus tankmates? Thanks again. Laura
<Laura, quite right, and I knew that. Forgive my confusing
mistyping. Snails, frogs alike should be fine with the Malawi salt mix
used as directed. In fact Xenopus laevis come from naturally hard
waters in South Africa, and there's some lab work to indicate
raising hardness increases reproductive success. A quick Google search
of Xenopus and hardness will reveal more. Cheers, Neale.>
Euthanizing Xenopus 2/15/09
Hello crew, I have a Xenopus froglet that has what appears to be a very
painful condition. I've included pictures. He is currently in a
hospital tank with a dose of Maracyn. His condition has been unchanged
for several hours. He's not eating. Actually I can't say for
sure when was the last time he ate, because up until this morning
he's been in a 55G with 5 brothers and sisters. However, I can say
that up until this morning he was swimming and behaving normally
otherwise. A few days ago I noticed that his tummy looked swollen and
hard and his legs looked unusually skinny, but since everything else
seemed ok, I just kept an eye on him. This morning I noticed what, at
the time, appeared to be a small scrape on his side and decided to move
him to a hospital tank for treatment. Seconds before catching him, I
looked for him and noticed nothing out of the ordinary except, of
course, his still swollen belly. I placed a large plastic cup in the
tank and gently encouraged him to swim into it. This was much easier
than I had expected. Then transported him, in the cup, to the Q Tank.
At no time, did I net or handle the frog directly. Upon placing him in
the Q Tank, I immediately noticed the protrusion. At any rate, I
don't think it's looking too good for the little guy and would
like to minimize his suffering if possible. So, I read the article
about Euthanising fish, very informative, but I have a question. If I
were to use the clove oil method for a frog would it be the same
painless process? I ask because the frogs have to surface to breathe,
and drowning doesn't seem to me to be an easy passing. Thanks, as
always, for your input. Laura <Hello Laura. Methods for euthanising
amphibians are not the same as those for euthanising fish. Unlike fish,
amphibians breathe air, and also unlike fish, they respire across their
skin rather than via their gills. In addition, amphibians are able to
tolerate much longer periods without oxygen than fish, so any methods
that rely on suffocation, such as the use of Clove Oil, won't work.
By far the best way to euthanise an amphibian -- and the only one I
will recommend -- is having a vet do the job for you. In terms of
background reading, I'd point you to two scientific commentaries on
the subject at the links below. Both of these describe appropriate
methods for painlessly destroying amphibians. If you choose the
euthanise your amphibian at home, you may still need to contact a vet
to get hold of the required chemical(s) and to discuss appropriate
dosages and methods.
amphibians don't move their gills and generally show less activity
than fish, it is critically important to follow these verified methods
to the letter. With fish it's pretty obvious when it's dead,
but this isn't true with amphibians (or indeed reptiles). Cheers,
Re: Euthanizing Xenopus 2/15/09 Thanks, Dr.
Monks. Laura <Hello Laura. Happy to help. Cheers,
F/U Euthanizing Xenopus 2/25/09
Dr. Monks and Crew, I wanted to thank you for your help with my little
froggie, and share some interesting information. As you suggested, I
took the frog to an exotic pet vet for euthanasia, the day after our
original correspondence. The vet said the frog had spina-bifida. Just
some random, natural developmental problem. So the frog's in a
better place, and I learned something new. Anyway, thanks again. Laura
<I've learned something new, too. Thanks for the update. We
often make reference here to genetic and growth issues that can effect
fish, but actually putting names to a particular syndrome is something
I'm not able to do. So this information is very useful. Cheers,
Sick Albino Clawed Frog? 5/14/07 Hey
there I have an Albino Clawed frog in my tank with a few fish and two
snails. The snails and filter help keep the tank rather clean and
it's a newer tank. I know the Clawed frog is going to get big
enough to eat the fish but for now he's just a little baby. (Barely
larger around than a quarter). Anyway... the last couple days I've
been noticing his belly is looking a little swollen on one side. Then I
woke up today and it's -huge- (bigger than his head). It seemed to
blow up from just slight swelling... where I wasn't sure if it was
actually swollen or if it was just distortion from the angle I was
looking at him at. (He moves around a lot and it's hard to get a
good look at him!) Today he's just hanging right at the top of the
tank and man it's big. I've looked at several pictures of
Albinos with dropsy and it doesn't look like dropsy. I wish I could
get you a picture but no digital cam... it's only on his left side
so I'm thinking blockage. I read a post where someone had a similar
problem and you suggested a teaspoon of Epsom salt per 10 gallons.
I'm wanting to try this, in fact I have my Epsom salt and teaspoon
on hand and ready!!... But I'm worried that this may hurt my
snails. Should I take my snails out of this tank and put them in the
other tank before I try to salt the water? Thanks! Erin in Arkansas
< Your frog has eaten an item that is being broken down by bacteria
and not being digested by the frog's stomach juices. As the
bacteria break down the food item they generate gas and expand the
abdomen of the frog. In fish we use a medication used on Protozoans
that may work with your frog. Try some Metronidazole found at some fish
stores or can be found online. I have not heard of Epsom salts being
used on frogs but they can tolerate some salts in the water so I would
give it a try but I don't think it will be effective.-Chuck>
Bloated African clawed water frog 5/8/06 Hello: I appreciate
any help you could give me. I have a 15-16 year old African clawed
water frog named May. <This is an unbelievably "ripe old
age" for Xenopus> She is 6 to 8 inches long. She has been very
hardy and healthy. I have never done anything special for her. She eats
ReptoMin pellets. That's all she has ever eaten except when I once
made the mistake of putting goldfish in her tank. She has lived through
several near disasters. I haven't been diligent about cleaning her
water. She has tolerated the lack of good care all of these years. Now
she is bloated horribly. But she acts normal, still wants to eat, moves
around, comes up to the surface. She has been bloating slowly for
several months, maybe up to six months. I have had personal crises so I
haven't been able to focus on her. I have read online that I could
maybe use Maracyn 2, maybe aquatic salt, MelaFix, stress coat. Her
water had a lot of "stuff" on top of the surface recently. My
daughter recycled her water, using Genesis in the tap water she added.
We have always used Genesis to remove the chlorine. What is the best
way to treat May? <... I'd go with the Minocycline... the
Maracyn2 product> How much longer can I expect her to live? We have
never used soap to clean her tank, but is there something I can use to
disinfect it since she might be suffering from some bacteria? <Mmm,
best to just use clean water, rock salt...> If I use Maracyn, how do
I know what dose and how long to treat her? Thank you for any help.

three days. Bob Fenner>
Amphibian Ailments (4/2/2004) Hi
your site was suggested to me by a rep a pet land. <A well informed
pet store employee> I have 2 African albino clawed frogs and one of
them seems to have some thing wrong with its foot. It looks like
skin is peeling off, or shedding. Its also blood shot. <Could be
bacterial or fungal...is there any "fuzziness" or anything
indicative of a fungal infection, or is it more red and swollen,
possibly indicative of a bacterial infection? As a side note, do check
your ammonia levels, and I assume you are not using chlorinated
water?> I at first thought that it might of hurt it self or the
other frog bit it. But today it looks a little better. But now if you
look at it, you can see the bones on the foot. <Not good. Does it
appear to be spreading? Any red\swollen skin or any red "blood
poisoning" obvious in the legs\blood vessels? Frogs of this
species are especially susceptible to "Septicemia"> Would
you guys have a idea as to what it could be? The guy at Petland thought
that it might be a fungal infection, but the other frogs seem ok.
<Probably bacterial (Septicemia), a nasty and all to common
infection of these animals.> If you can email me back at * I'd
be grateful. <Try treating the frog with 'Triple Sulfa' by
Aquarium Pharmaceuticals or Tetracycline (available from Kordon and
other vendors, shouldn't be hard to find at your local pet store).
Do this in a separate container of tank water or a quarantine tank.
Dose appropriately and make sure to keep the water heated. If you
don't notice any improvements in 4-5 days, do send me another
email, along with the aquarium size, tankmates, and a picture of the
frog if possible> Thanks <No problem, let me know if your frog
doesn't improve in health in a few days. M. Maddox>
Frogs and drugs (no toad licking
here) Hi, I just treated my freshwater tank for what appears to be
velvet. I bought Greenex to treat the tank. I have an African Albino
Clawed Frog in there that reacted badly to this. Am I going to lose the
frog due to using this product? Thanks, Lynn <wow... I must admit
that is doesn't look good for the frog. Do remove it from the tank
or the medication from the water immediately (water changes and
carbon). Medications that include metals (like copper) or organic dyes
should never be used on invertebrates or scaleless animals (including
some fish). The frog was indeed overdosed... but don't give up,
please. They are hardy. Fresh water ASAP. Best regards,
Re: frogs Anthony, Thanks for
your reply. The frog was dead by morning : ( I sure felt bad. The rest
of the fish are dropping like flies. I wish that I had gone on line
before I bought the Greenex. The product said it was safe, HA! Now I am
just trying to save as many of the fish as I can. Thanks, Lynn
<alas... sorry for the loss too. Some such meds are not necessarily
bad, but rather cure or kill remedies. For virulent infections they may
be called upon. I personally do not care for this medication in most
applications, but many fine aquarists have had very favorable results
with it. I do not recall the manufacturers warning to know if it
considers invertebrates, amphibians and the like. I suspect it must
mention scaleless fishes/animals though. Best regards,
