Goldfish growth     10/18/18
<Have to delete your msg. as you've crashed our mail server. See our file size requirements>
My goldfish (Ronald) has a weird bump on his side. I've had him for about a year and it just recently developed (first noticed maybe a month ago) It started out small but it is getting bigger. And now it looks like he might be getting another one. I cannot figure out what it is, nothing really seems to match perfectly. If there is any change you might know? I would hate for him to be sick and require treatment he's not getting. He is acting perfectly normal otherwise.

Question Regarding African Clawed Frogs     10/18/18
Hi there, I was wondering if there are any sorts of diseases/bacteria/etc. that are transmissible from ACFs to humans.
<As with any aquatic pet, the most common transferrable diseases are Salmonella-type food poisonings. Not from the animal itself, but from decomposing organic matter around the aquarium. Touch the tank, touch your mouth, and boom, the bacteria can get inside you. Of course most people are fine and never experience a problem, it's a good habit to treat an aquarium as you'd treat raw meat, and after handling, wash your hands accordingly.>
About a week and a half ago, I ended up having some frog water splash into my eye, not a huge amount, but enough that I decided to rinse the eye out with eye wash once I had finished with the water change. Around 4 days ago my eye started becoming very bloodshot and hasn't cleared up so far. Maybe I just hit my eye in my sleep and didn't notice or something but just in case, it'd be nice to know if there's anything in particular to keep an eye on. Thanks.
<Unlikely to be anything serious, but if bacteria-laded water or organic material gets in the eye, it can trigger conjunctivitis. No different to when you get soil in your eye, or anything else not completely clean. Best to consult your GP or an optician, who'll likely suggest the use of some sort of antibacterial eye drop. Cheers, Neale.>

Undecided about how to treat further     10/18/18
Hi crew!
I originally added 7 peppered Corydoras to a filtered and cycled quarantine tank. They have been in there for almost two weeks (I plan on quarantining for 4 weeks).
I purchased them from a local chain fish store. They told me that they had been treated with Quick Cure for about a day while in display tank.
<Mmm; the ingredients are too harsh (formalin, Malachite Green) for Corydoras, most catfishes>
My tank parameters are 0 ppm ammonia and nitrite, 5 ppm nitrate, pH 6.8, temp 76°F, Aquaclear filter and airstone, sand substrate, driftwood and wood stone.
<Sounds good>
I lost two corys the second day after I added them to my quarantine tank. I did carefully acclimate them and they didn't seem stressed afterwards. I don't normally add medication to the tank unless I notice a problem. The second morning one of the corys had severe pop eye in both eyes. Eyes were not cloudy but were severely swollen, one eye had actually ruptured.
<?! What happened here? Something/s very wrong... too much difference twixt the waters? The fish too long in the bag, overheated...? Some source of overt poisoning? I'd removed the driftwood, add activated carbon to your filtration>
A second Cory had mild pop eye in both eyes and a third was on its side breathing rapidly (no pop eye). The Cory with the severe pop eye died that morning as did the one on its side with respiratory issues. I did a small 15% water change (parameters were normal) and dosed the tank with Kanaplex. I did a full three dose course of Kanaplex, then 48 hours after the last dose did another water change (25%) and have basically just been observing for further symptoms. The Cory with the mild case of pop eye recovered completely and up until today everyone has been eating and acting normal. I did have one that was away from the group quite a bit and not as active but still coming out to eat.
This evening when I got home, one of my corys (I believe the less robust Cory) was basically floating near the surface; still alive, he will swim a bit when nudged, but not looking well. No sign of hemorrhage under skin, body normal with good slime coat, fins and barbels normal, respiration normal but extremely lethargic and just floating at surface. Upon inspection he looks perfectly normal. The remaining 4 corys are eating and acting normal.
I do have Metroplex on hand as well as General Cure. Do you think I should try adding Metroplex to the water column or food?
<I would not. Metronidazole has specific uses. Unless you/I can detect the organisms involved (if any; which considering the rapid onset...) I would not treat>
I do a water change every 5 days (tomorrow is 5th day) but even though I match pH and hardness and temp, I'm afraid a water change will push the sick Cory over the edge. Although the antibiotic appeared to resolve the original problem, I don't want to repeatedly dose the tank. I'm wondering if there could be an underlying parasitic problem (gill fluke?). None of the corys look emaciated and even the sickly one has a normally rounded belly. Any suggestions?
Thanks crew!
<Corydoras paleatus is a hugely aquacultured species of long use; quite labile in its placement, range of conditions. Again, I suspect either trauma or toxicity at fault here. Would just remove the driftwood, add carbon... Bob Fenner>

Re: Possible Betta Tumor?
Thank you for confirming what I thought - I really appreciate it!
Even when you think you know then knowing that you can’t do any more is reassuring and to be fair most vets look puzzled when I ask them so it’s really really appreciated. And thank you for all the fish guides! When I first got my boys they were immensely helpful as I hadn’t had Bettas for about 15 years and frankly I probably could have created better conditions for them last time compared to the mansions they have these days ��.
Have a lovely evening!
<Wow! Thanks for these kinds words, and taking the time to write us. We do appreciate that. Hopefully your Betta will live a happy life, if not perhaps quite as long as it might have otherwise been. Cheers, Neale.>

Re: Marine Velvet Dormancy
Thank You Wil!
<You´re welcome Anik!>
Love your teams’ advice. It definitely helps to quell much of my on going paranoia.
< Hahaha....there´s no need to be paranoid! just make wise, on impulsive decisions...we are glad to be helpful…>
I’m secure and confident in my overall QT scheme and don’t plan on adding anymore fish in the future...until I upgrade which is a near term possibility.
<That´s good to know>
Yes the Naso will get a larger home, gladly he’s only 2 inches right now.
<Yes, you still have time to plan the upgrading >
I won’t move the fish then. Thanks again for your advice!
Have a great night.
<Have a great night too!>

Possible Betta Tumor?      10/16/18
Hi guys
I’ve been reading your page for a while and have managed to so far keep my three beloved Bettas happy and content... a few months ago one of my boys however started developing a black growth as you can see in the photo that is definitely getting bigger...
I don’t know if this is a tumor or something treatable?
<Almost certainly not.>
He seems active and just as daft as always and the tank is testing normal, regular changes and weekly tests etc all as they should be...
Is there anything I can treat him with or is it just a matter of letting him carry on until his quality of life reduces and then letting him pass quickly?
<Precisely. Tumours and other sorts of growths, whether benign or malignant, are not uncommon in Bettas. There's no obvious explanation beyond inbreeding, and certainly no clear treatment. Often benign tumours cause no immediate problems, and if your Betta is otherwise happy, I would not be overly concerned just yet. Cheers, Neale.>

GF ish, no data, reading...       10/16/18
Any ideas what is wrong with this fish? Dark spots and hanging out at the bottom.
<Mmm; appears to be septicemic... burnt... Water quality issue? What's your test kits readings telling you? What re set up, maintenance, foods, feeding? Have you read re on WWM? Do so. Bob Fenner>

Marine Velvet Dormancy      10/16/18
Hello Bob and Team!
<Hello Anik, Wil this morning>
Hope you are doing well. Like any reefer, I’m constantly reading about preventing any disasters.
<Like any good/responsible reefer!>
The topic of my paranoia this week is Marine Velvet. Some facts about my setup: my display tank is 100G mixed reef; shows no signs of marine Velvet and never has. There’s been a sign of ich once, which made itself visible on bullied fish but that cleared up on its own and everything has been clear since. Btw I QT everything, and medicate every new fish with PraziPro and Cupramine and observe after.
<Quarantine is fine but there´s no need to medicate if fish are not sick, treating healthy fish just makes any pathogen more resistant to medications and this could be a problem in the future if fish happens to get sick.>
Typically I QT for 3-4 months.
<4-5 weeks is more than enough>
The one time I didn’t was when I added a mandarin to my DT, no QT :(.
Current roster, two ocellaris clowns, male Anthias, melanurus wrasse, yellow Coris, yellow flanked fairy wrasse, flame angle and tiny blonde Naso.
<I hope you are aware that the Naso tang will need a bigger tank (a few to several hundred gallons) to have a long, healthy life.>
Anyways, questions; is it possible to have marine Velvet present in a tank but kept at bay from infestation by keeping water parameters in check and general conditions clean/healthy/happy to hold the velvet in check?
<Actually that is how it works; velvet as well as other diseases are always present in the system water but with good maintenance and feeding practices, you can keep them away of your livestock indefinitely.>
What I am getting at is can a fish have velvet for months and not be symptomatic until something triggers it?
<As I mentioned, disease is always present but only attacks your fish if its immune system is compromised.>
Depending on your answer, I may go against your advice from a few months ago regarding Ick in the DT (referring to that one fish mentioned above); I may just move all my fish to QT and treat them and run the tank fallow out of straight paranoia.
<I don´t see the need of treating your fish without been absolutely sure they are sick, you are going to add unnecessary stress. I wouldn´t move them to QT>
I have two wrasses and a flame hawk in QT right now and would like to plan my next steps to add them to DT...but would like to avoid disaster.
<If you have quarantined/observed them for at least 4 weeks, you may transfer them to the DT.>
Thanks Team! Anik
<You´re very welcome. Wil>

Royal Gramma Flashing     10/13/18
<Hello Tim>
I am looking for some insight and/or recommendations regarding the recent condition of my royal Gramma and Jawfish. This is my first tank, but I have spent countless hours reading books and reviewing forum posts on the hobby. There is just so much information out there and some of it is conflicting. Any thoughts or suggestions you can provide on my situation would be greatly appreciated.
<Let´s see>
- BioCube 32 LED FOWLR
- 3" of substrate
- Filter floss on top shelf of sump
<Hopefully rinsed VERY frequently>
- Large particle lignite carbon in bag on second shelf of sump
- Heater set to 78
- 1 powerhead w/ variable flow
- 20 lbs mix of live and dry rock (50/50)
- AccuraSea 1 Synthetic Seawater Mix - Two Little Fishies
Current Occupants:

- 2 turban snails
- 2 Astrea snails
- 1 Nassarius snail
- 1 cleaner shrimp
- 1 royal Gramma
- 1 yellow head Jawfish

- pH = 8.0 – 8.2
<Aim for 8.3 using a quality buffer>
- Ammonia = 0 ppm
- Nitrite = 0 ppm
- Nitrate = 10 – 15 ppm
- S.G. = 1.023
<A bit higher would be better,1025/35 ppm (natural sea water salinity>
Daily: Feed fish LRS Reef Frenzy; clean algae as needed; and monitor fish.
<A more varied diet would be better, have you try Spectrum pellets? "Thera +A" helps treating parasites; a vitamin supplement is also needed, either added directly to the tank water or by soaking the food.>
Weekly: Replace filter floss; check water parameters; vacuum substrate and conduct 5 gallon water change.
Monthly: Replace carbon.
<Must be remove when medicating the tank>

I started the tank approximately 5 months ago. The initial cycle completed approximately 3 months ago, (i.e., no ammonia detected for the past 3 months). I purchased the royal Gramma from my LFS about 2 months ago without a quarantine.
<The root of the problem, ALL fish must be quarantine at least for 4 weeks>
The Gramma was initially skittish, but it calmed down after about 48 hours. Gramma has been eating like a horse ever since and appears noticeably larger then when we purchased it. I then added the above CUC (no quarantine) to deal with some algae growth. I lost 2 Nassarius snails within the first week, but the other snails looked fine.
<What about calcium levels?>
I attributed the snail loss to my failure to conduct a drip acclimation on the snails.
The CUC has kept the algae in check. About 2 months ago, I purchased a yellow head Jawfish (no quarantine) from my LFS. The Jawfish was extremely skittish for about 24 hours, but he calmed down.
<Normal behaviour for new fish>
He has built some burrows for himself and has been eating well ever since.
A little over two weeks ago, I noticed the Gramma was flashing. Not much, but if I watched for about 20 minutes, I would see the fish dart around and then swim into the live rock or side of the tank multiple times in a row. The Gramma did not have any small white spots (ich), but I did notice some slight discoloration around the purple head and gill area. The Gramma was also hanging out a little bit more in the back of the tank. However, the Jawfish seemed fine at this time. My LFS examined pictures of the Gramma. They suspected some type of parasite, but they did not think it was ich.
<I agree here with your LFS, not a visible parasite but an internal one, this is why quarantine is a must, even if there is no noticeable illness.>
On the advice of the LFS, I did the following:
- Added cleaner shrimp (no quarantine)
<Not very helpful if parasites are internal>
- Increased thermostat to 81 degrees
- Lowered salinity with 2 gallon exchange of salt water for fresh water
- Dosed PraziPro for potential flukes
- Removed carbon from sump
- Attempted a fresh water dip for the Gramma, but he was too quick for me to catch. I gave up trying to catch him after 3 failed nights of chasing him with nets and bags. He is now terrified of the nets....
<Would be worthy to take out all the rocks so you can catch the Gramma Loreto and treat it with copper on a separate tank>
The above modifications haven been in effect for the past two weeks. While I have observed the cleaner shrimp briefly working on the Gramma (so cool), I have not otherwise observed any improvements with the Gramma's condition. In fact, I think the Gramma's discoloration may be even more pronounced now (see attached pic), and the flashing has continued at about the same rate. He does seem to be back in the front of the tank a little bit more now. In addition, I noticed the Jawfish is now rubbing his head in the sand occasionally, which is a behavior I have not previously observed.
<Disease is spreading>
I have only seen this a few times. The Jawfish otherwise looks and acts normal. Both fish are still eating like champs.
One other note, I think the Gramma and Jawfish may have had a little tussle about 3 weeks ago. I say this because I noticed the Gramma was occupying the main burrow built by the Jawfish. They seemed to have sorted this out now, because the Jawfish moved into a new home burrow. There have been no other signs of aggression (jaws wide open/nipped fins/chasing/etc) between the two fish, but I am not watching them 24/7.
<If aggression is taking place(even out of your sight),it could be an added factor, since stress is a direct access to most diseases>
Plan Forward:
My original thought was to setup a quarantine tank to dose the Jawfish and Gramma with copper and to let the display tank go fallow for 2 months. After researching on this site and others, I think this may not be the best option.
<Not the easiest but certainly a wise option>
The quarantine tank and meds will certainly stress the fish out, and I am not certain I am dealing with a parasite. My new plan was to reset the salinity and temperature to my original points and wait and see. I will still go ahead with purchasing the quarantine equipment for future fish/corals/invertebrates, but I will hold off on adding anything to the tank until this situation is resolved.
<It won´t solve with the current treatment>
Do you have any questions, suggestions or advice regarding the Gramma/Jawfish? Again, I am new to the hobby, and it is quite possible I am missing something basic here.
<Keep Reading...>
Separate/bonus question, would it be an overstock to have a 1 Jawfish, 1 Gramma, and 2 ocellaris clownfish in the BioCube 32?
<Bioload is fine according to your tank´s capacity>
Thank you in advance!
<Welcome Tim.>
<Same to you>

Re: Peacock Gudgeon Constipation?     10/13/18
Is there an antibiotic that you would recommend?
<Anything for Finrot worth a shot. Kanaplex is good, and the old Maracyn 1 and 2 combo is well regarded. Just avoid the "new age" medications such as tea-tree oils that really aren't very effective. Salt isn't much use,
either. Cheers, Neale.>
Re: Peacock Gudgeon Constipation?     10/13/18

Is there an antibiotic that you would recommend?
<PS. Outside of the US, it may difficult to get antibiotics without a prescription from a vet. Here in the UK, I favour a European product called eSHa 2000 that's effective and tolerated well by even sensitive fish.
Cheers, Neale.>
Re: Peacock Gudgeon Constipation?     10/13/18

Ok thank you very much
<Most welcome and good luck. Neale.>

ACF Tadpole Die-off     10/13/18
Over the last few months I decided to raise around 80 African Clawed Frog tadpoles and for the most part, things have gone fine. 3 days ago, I was down to my last 4 tadpoles, in the 10 gallon tank, within 2 days, 3 of the
last 4 had died off and my last tadpole looks like this (see attached image).
<I see.>
In the last day, the end of the tail went limp like the other 3 before they died but in this case, the tadpole's tail end has essentially just rotted off, it's the only occupant of the tank nothing could have bitten it. All of the water parameters are normal, no ammonia, nitrites, nitrates,
<I doubt nitrates are zero. So if your test kits are offering these numbers, you probably should distrust them. Zero ammonia and nitrite are certainly possible, indeed, preferred; but since nitrate is the end product of filtration, it should accumulate over time between water changes.>
the GH and KH are constant.
<Constant what? As a reminder, neutral, medium hardness water is the ideal.
Water temperature should be around room temperature, 18-20 degrees C being ideal for the classic Xenopus laevis species most widely traded. Avoid excessively high temperatures, and similarly, avoid chilling and/or exposure to cold air. Xenopus tropicalis is less commonly traded, and requires warmer water (24-28 C) and prefers softer water chemistry.>
About 2 weeks ago, when there were 7 left, I altered the water change schedule to 50% every 3 days since the parameters were staying constant.
<Do remember water changes need to be more or less daily, and ideally twice daily. Xenopus tadpoles, like baby fish, are very sensitive to 'old' water, especially in small tanks. The easiest approach is to reduce the number of
tadpoles per tank, which puts less pressure on water quality, and in turn makes it easier to rear them successfully. Trying to rear huge numbers can be an overwhelming task. Do be ruthless about removing uneaten food and
dirt (turkey basters are ideal for spot cleaning) while also ensuring more, small meals rather than 1-2 big meals.>
The only issue I've had was the heat going out in the house for 3-4 days but the lowest the house dropped to was about mid 60s (F).
<Might be a bit cold, especially if there were cold draughts of air as well.>
As of 2 days, after the first tadpole had died and the others were acting sluggish, I restarted daily 50% (looking back, I would've gone with 30% but I've been a bit burnt-out these last two weeks) changes on the 10 gallon. My
thinking was that perhaps the water wasn't being properly oxygenated on the every 2 days water change schedule but now with this tadpole's Finrot-like symptom, I'm just baffled - each of the others had the same tail tip droop
but none of them lasted long enough for it to progress to more than a droop. (Note: the final tadpole just died early this morning but I'd still like to figure out what on earth happened to prevent anything like this in the future should I decide to raise more tadpoles at a later date).
<While the tail-drooping is remarkable, it may be more a reflection of general failure to thrive rather than some specific disease or problem.>
Additionally, I've fed them Xenopus express tadpole food daily for the past 160-odd days since the tadpoles hatched. Over the last few days, after the heat went out, the last 4 tadpoles all became lethargic and stopped eating/actively swimming. Each of them were receiving about 0.3ml of the tadpole suspension a day in the week prior every afternoon, Xenopus Express' feeding instructions assume you're raising the tadpoles in bulk and don't translate well to smaller numbers. I had almost no issues while I was dealing with a large number of tadpoles but once I was under 20, I found myself a bit uncertain of a good feeding schedule/amount, I'd welcome any suggestions on how much to feed a single tadpole.
Thank you for any advice.
<Hope this helps. Neale.>

Re: Peacock Gudgeon Constipation?     10/12/18
So far he is still fine. Still has a bit of prolapse, assuming it was a messy bite. Hopefully it isn't as bad and it can heal naturally. I have cherry shrimp in the tank so meds is off limits and catching him is somehow a pain, others I can catch with my hands, but this guy is very evasive. So QTing is pretty much impossible without destroying a bunch of plants just to catch him. Thank you very much.
<Understood. Antibiotics should be safe, even with shrimps and snails, though you could just watch and see what happens for now. Obviously yes, organic dyes, formalin and copper compounds are not safe with invertebrates. Cheers, Neale.>

What is growing on and near my live rock?     10/12/18
Hi folks,
<Hey Shawn>
I have been using your site for many years and it has always been a blessing and answered every question I had!
<Glad to know it has helped you that much!>
I have a 90gal tank with quite a bit of live rock and very few inhabitants currently (few small snails). Getting the tank ready to stock once again and (outside of some unwanted algae), I have some things that started growing that I have not experienced before. I can't seems to find exactly what these tree/twig looking things are that are growing on and next to my live rock. Kind of remind of Mangrove roots here in FL. Here is a pic of them in the tank and one that got temporarily de-rooted as I was
cleaning tank and bedding while readying for next participants.
<This is some kind of calcareous algae, looks like Halimeda incrassata.>
Regards, Shawn
<Have a nice day. Wilberth.>
