A worm question (Horsehair worms; stingrays)   10/17/08
Hello,
<Hi,>
was just wanted to know I notice some of my ghost shrimp have worms in there intestines are to believe they are Gordian Worm, a.k.a. Horsehair Worms...one died bc the worm killed it but I never notice them b4 on my shrimp I feed these shrimp to my Motoro stingray which I have had for about a week I know they are prone to roundworms and tapeworms but I was wondering if I did feed some shrimp that had these in them can they kill my ray I called the pet store where I got my ray and they never really heard of these worms really and are not sure if they will harm the ray they feed there ghost shrimp to there rays and had no prob but they never looked at there shrimp to see if they had worms so they could be feeding ones that do so I don't know what I should do I don't want my ray to die and I don't know if I should get new shrimp the other ones seem to not have these worms in them..should I continue to feed them to my ray or go and get new ones??????

HELP!!! PLEASE KINDA SCARED FOR MY RAY I LOVE HIM!!!
<Horsehair worms are not likely to cause your Ray any harm. Most parasites are species-specific, and while they may be harmful to the shrimp, they are unlikely to adapt to the particular anatomy of your Stingray. If you're really that bothered, don't use the shrimps. Earthworms are a very safe food if collected from an area that is "organic", i.e., not sprayed with chemicals. Most rays love earthworms. There's no reason to use live food with most Stingrays anyway, and a varied diet of mussels, prawns and squid is easily provided using foods sold for humans.>

Ghost shrimp/jewel anemone hlth/ID  - 07/19/08
I can't seem to find an answer for my questions.#1 I bought some ghost shrimp from my LFS and I noticed they had some white dots on their body, is this normal or some sort of disease?
<Mmm, likely more the latter... not communicable though. These sorts of markings show up in specimens that have been kept in poor conditions>
#2 I have a large colony of jewel anemones
<There are a few species that go by this name... Is this a Corynactis? Which do you have?
and can't find any info on them any where can you tell me or give me a link to some information on them? Thanks for any help!
<Bob Fenner>

Re: Ghost shrimp/jewel anemone 07/20/2008
Wow I didn't think I would even get a reply yet alone a reply so quick!
So then it would be safe for my fuzzy dwarf lion to eat said ghost shrimp his health is of great importance to me. #2 yes my jewel anemones
do resemble Corynactis and now I have their scientific name I'm finding a lot on them. I saw tanks full of them at Chicago's Shedd aquarium
that's were I got the jewel name from. thank you very much. I'm sure your words of wisdom have prolonged the lives of many of our aquatic
friends!!!
<<Yes, the ghost shrimp are fine for the lionfish. Really glad you found the correct name for your anemone, all helps towards providing a better environment for them. Thanks for the follow-up, hope this helps. A Nixon>>

Keeping Ghost Shrimp  7/24/06
Hello!  
<Hi Cathrine, Pufferpunk here>
I am hoping you can help me understand why my ghost shrimp keep dying hours after being added to my 5 gallon aquarium.  In this tank I have 1 male Betta and 1 Otocinclus.  Originally the shrimp was to be the cleaner but since I am not having any luck with them I got the Otocinclus.  I would like to add at least 1 ghost shrimp because in the short time they have been alive I find them fascinating.  I suspect something with my water is not compatible with the shrimp because they are fine until they have been added to the tank.  This tank is heated and stays around 77 degrees (unfortunately it can not be adjusted).  I have a hang on the back filter rated for 2-5 gal and an under gravel filter.  The tank has been running for 2 months.  Nitrate is at 20ppm, Nitrite is 0, Hardness was at 0 but since the shrimp seemed to do well in the spring water they were in before being added to the tank, I added some to the tank and it is now at 75ppm.  Alkalinity is 300ppm.  pH is 8.4 (Both of these are high and I am wondering if one or both might be the problem.) Ammonia is 0.  I have been using treated tap water only, which is softened with potassium chloride. (Possibly another cause?)  The beta and Otocinclus are doing fine so I am not sure where the problem might be.  The first time I added 1 shrimp (had only treated tap water in the tank so hardness was at 0), he died within an hour and half.   A few weeks later I added two more thinking maybe the first one was just a "bad" shrimp.  They both died within 2 hours.  After that I started adding the spring water, topping off my tank so my hardness had increased to 75ppm.  Two more weeks later I added four shrimp trying to increase my chances of one surviving but they only lived up to 5 hours.  They seem fine then all the sudden fall on their side and finally end up dead on their backs.  Neither the beta or Otocinclus are bothering them.  So not knowing where the problem lies I am beginning to wonder if I should drain the tank and refill it with all spring water.  Sorry for such a long email but I wanted to give you as much information as possible.  Thanks so much for your time!

African Dwarf Frogs and fish medications    7/13/06
Hello, my name is Robin.
I have a 45 gallon tank that houses one African Dwarf Frog, 4 Ghost Shrimp, and 12 Bronze Cory Catfish.  
Yesterday I noticed that some of the baby (I say baby, my original three bred successfully in my aquarium about four months ago) Corys have fuzzy fungus  
growth. I have Applus+  Anti-Fungus Fungus and Fin Rot Treatment, whose  main ingredients are Malachite Green and Hydrochloride.
<Toxic to your Frogs and Shrimp>
I wanted to check before I add anything to the tank, because I'm concerned about the frog and the shrimp. Will I have to move them to a different tank while treating the catfish?
<Yes... and do check your water quality... The Corydoras would not "get" a fungal/bacterial infection if all was well here>
Is there a more "frog friendly" treatment for the catfish? I know that the Anti-Fungus treatment is potentially harmful to scaleless fish, and frogs absorb things through theirs, so I don't want to  poison the frog.  
Thank you very much.
Robin
<You need to separate the non-fish. Bob Fenner>

Ghost shrimp, Acanthocephalans, worms in general...   1/15/07
I just bought a few ghost shrimp and everything appeared to be going fine until today, when I noticed one of the shrimp had a worm in it.  
<You have good sight>
After a mild freak-out I managed to do some research on the internet and found out that it was most likely a horsehair worm.
<Yes, possibly an acanthocephalan...>
Unfortunately, I haven't found
much useful information regarding my situation beyond the initial identification.  The infected ghost shrimp was in a tank that contained some guppies as well as other ghost shrimp.  Could the worm have possibly laid eggs in my tank?
<Could...>
Would I be able to see them?
<No, too small>
Should I worry about the larva (assuming there are eggs and that the eggs will hatch) infecting my fish and other ghost shrimp?  
<Mmm... possibly the shrimp... not likely the fish... May well be that the life cycle of this parasite is "complex" and that your tank is missing an/the intermediate host... likely guppies are not definitive here>
I know that the young are parasitic, yet I am not completely sure if they use fish as hosts.  The ghost shrimp was in my tank for less than 24 hours.  Are they dangerous to my fish?
<Again, not likely>
Should I assume that my whole tank has been infested?  Is there anything I can do to stop the infection, assuming there is one, without harming my fish?  
<... I would do nothing... but there are some useful anthelmenthics... Praziquantel, Levamisole... you can search re these on the Net, WWM...>
Currently, all of the other inhabitants of my tank seem fine, and there is no evidence of other horsehair worms infecting my tank.  I hope I am overreacting to this tiny worm.
<Mmm...>
  Please set my mind at ease. Should I be freaking out about the possibility of infestation of my other fish and ghost shrimps?
Thanks,
Lauren
<How to put this... there are actually several... as in many, species of worms... living in your system... in your own personal world... This one is likely only detrimental to the shrimp that are hosting large individuals... in non-propitious circumstances. I would not panic here. Bob Fenner>

Wood Shrimp / Atyopsis Losses - 03/07/2007
I just lost my poor little wood shrimp this morning, this is the second one that has died in more or less the same way. They molt, and then they just keel over dead.
<Perfect observation - some very important clues, here.>
I haven't gotten either of my deceased shrimp past the first molt. Water conditions are as near perfect as can be, and the fish in the tank are 3 platies, 5 zebra danios and 2 Cory catfish (15 gal tank.) The shrimp had good hidey holes etc, and was an enthusiastic eater- until he died! What happened to my poor shrimp?  
<There are a number of things that may have contributed to this - have you ever used copper medications in the aquarium?  Any other medications?  Use water out of the tap, and have copper pipes?  The primary thing, though, is likely an iodine deficiency and/or a calcium deficiency.  If your water is relatively "hard", I'd wager money that it'll help immensely to supplement your water with iodine.  Kent iodine or Seachem iodide, or other iodine solutions for marine/reef use would be beneficial to you, here - but DON'T use the marine dose, instead just a drop or two per ten gallons every week will suffice.  After starting this in my tanks, I no longer lost shrimp mysteriously.  I hope the same will happen for you!>

Freshwater Amano Shrimp - Hiding or? 2/15/07
<Oh man! I wish Sabrina were here... She is absolutely passionate re FW shrimp...>
I have a 30 gallon octagon freshwater tank with 5 neon tetra, 6 zebra danio, 1 gold danio, 2 Julie Cory, 1 peppered Cory and one striped Kuhli loach. When I asked the LFS what I should add to help with the algae problem he recommended Amano shrimp.
<Neat choice>
I asked for 3 (a baby got scooped up in there with them) so I ended up with 4.  Purchased Friday 2/9.  I acclimated them slowly just like I would for saltwater shrimp
<Good>
and then put them in the tank.  The baby I found dead the next day, and two are MIA.  The first day they were all out on the driftwood picking off the algae.  The 2nd day is when I found the small shrimp dead and it turned a reddish color.  Since Saturday I've been searching for the shrimp.
<This species and most all other FW shrimp are reclusive, retiring>
At fish feed time one shrimp comes out and then poof he's gone.  At night I've only seen one shrimp (using a flashlight to look for those glowing eyes).  Tuesday morning afraid that I might have some dead shrimp rotting I went in and removed the rocks and all but one piece of driftwood.  Again I only saw one shrimp. no bodies, no shells, nothing in the filter.  Tank is covered and nothing on the floor.  I'm at a loss.  Can they hide that well?
<Mmm, yes>
Any of the above animals possible culprits?
<Of the fishes you list, doubtful>
The shrimp are not small. about the same size as my largest danios. about an inch and a quarter.  In the beginning I did see one of the danios kind of nip at that one shrimp in passing, it scooted off and the danio went about its business.  I read that iodine should be added, but I've been using Amquel in tap water for water changes and I know my Salifert test kit will not give a reading because of the Amquel and I'm afraid to add iodine without testing.
<Mmm... an occasional (let's say with the interval of water changes) dosing at a low level (a few drops of a stock solution period)... is a good idea... this material is very transient... won't overdose... much the same as iodated salts for human consumption>
Which water conditioner/dechlorinator should I use instead of Amquel so that I can test for iodine?
<I would likely not actually test...>
  Tank parameters as follows (testing done Wednesday night):
0 Ammonia
0 Nitrite
0 Nitrate
0 Phosphate
7.2 pH
As this is a tall tank I have two thermometers one on the substrate and one near the top.  The heater is placed closer to the bottom.  Bottom temp is usually around 76°, top temp usually around 79°.
<Interesting... this is a surprisingly large difference. Do me a favor and "switch" thermometers and see if they register this difference still>
I have Amazon swords and java ferns all of which I constantly have to wipe algae off the leaves, two pieces of driftwood, 3 large rocks.  So there are plenty of hiding places.
Again, thank you so much for your advice/comments.
Regards,  
Debra P.
<I would not be overly concerned re the consequences or possible loss of the Amanos... And I do encourage you to consider adding SAE's here for algal control. Please do take a read re: http://www.wetwebmedia.com/FWSubWebIndex/saes.htm

Wood Shrimp - Atyopsis moluccensis - Mysterious Molting Deaths - 03/17/2007
I just lost my poor little wood shrimp this morning, this is the second one that has died in more or less the same way. They molt, and then they just keel over dead.
<Good observation - and a common occurrence, unfortunately.>
I haven't gotten either of my deceased shrimp past the first molt. Water conditions are as near perfect as can be, and the fish in the tank are 3 platies, 5 zebra danios and 2 Cory catfish (15 gal tank.) The shrimp had good hidey holes etc, and was an enthusiastic eater- until he died! What happened to my poor shrimp?  
<There are perhaps at least a few possibilities, but the likeliest are that they died from a toxin in the water (heavy metals, especially copper, that may be in tapwater are quite dangerous) or simple lack of iodine and/or calcium.  The realistic solutions to these problems are to use as "good" a source of water as possible, and to supplement with iodine - Kent or Seachem or other marine preparations will be fine, but do NOT use the marine dose - just a drop or two per ten gallons on a weekly basis is fine.>
-Jen
<I am sorry for your losses, and hope that your future shrimp will fare very well for you.  All the best to you,  -Sabrina>

FW, shrimp hlth... maint., Dracaena plants... non-aquatic   4/22/07
Dear crew,
First I would like to thank you for all the information you provide. Thanks to you I have a flourishing tank full of shrimp and fish.
Unfortunately I also have a flourishing problem. I currently have a 55 gallon freshwater tank that is cycling with 2 Cory catfish about an inch long, 2 glassfish, 3 ninja shrimp, and 1 bamboo shrimp that recently molted.
<Mmm, a necessary/compelled comment: Not a good idea to cycle a system with such livestock present... the shrimp likely molted out of stress more than all else>
I also recently added lucky bamboo
<Hmm? The Dracaena? Not really aquatic...>
and java moss. The problem started when one of the Hikari tropical sinking wafers that I feed my catfish fell into the java moss where my catfish could not eat it, before long it had white stalks growing out of it,
<The catfish or the wafer?>
the same thing happened to one of my ninja shrimps body after it died.
<Mmm, yes... likely "mycetes"... mostly fungal decomposer colonies>
I also noticed some white specks on the aquarium glass and when I tried to scrape them off they didn't come off.
<Use a single-edged razorblade if this is a glass tank>
Is this just a side affect of the tank cycling and if not should I be worried?
<Mmm, maybe so...>
All my ammonia, nitrite, and nitrate are where they are supposed to be.
I apologize if  you have already answered this question but I could not find it on your website.
Thanks,  Tuscan
<Mmm... the usual water changes, monitoring should do it here... Bob Fenner>

FW shrimp molt gone awry   6/24/07
Hey Crew. I have a female wood shrimp (Atyopsis moluccensis) that molted about two days ago. Something went wrong with the molt, and the plate over her "shoulder" area (over the walking legs) didn't form properly, it is flared out from her body, exposing the flesh underneath. She seems to be alright for now, although she's climbed up onto some roseafolia, and isn't moving around much, or fanning the water for food. I assume the risk to her now is infection, with her flesh being exposed to the elements. I would hope that this problem can fix itself the next time she molts; is there anything I can do to help her through this for now? Thanks in advance for your help.
<Greetings. "Faulty" moults are one of the risks of keeping any crustacean in captivity. The physiological process behind moulting is incredibly complex, and everything has to work 'just-so' or the whole thing messes up. The short answer as far as the aquarist is concerned is to [a] make sure water quality is excellent and appropriate to the species being kept (which typically means hard/alkaline); [b] the diet is correct and supplies all the essential nutrients, including trace elements (i.e., feed as varied a diet as possible); and [c] make sure the crustacean has somewhere to retire to during the moult so it cannot be damaged by other animals in the tank (i.e., some sort of cave). The problem with the family Atyidae (or fan shrimps) is they easily starve in aquaria. While not exclusively filter feeders, they aren't "scavengers" in any real sense, and do need regular supplies of nutritious food. So your shrimp should have been getting at least a couple of krill or a few bloodworms per day alongside whatever algae and detritus it was picking up in the tank. Failure on this count puts the shrimp at risk of starving, if not in overall terms of energy, then certainly with regard to specific minerals and trace elements it needs for moulting. (The parallel in humans might be anaemia -- it's easy to eat lots of food, and yet be anaemic, because the food you're eating contains too little iron.) In theory at least crustaceans can and do repair faulty moults "next time round" but as you say, there is a risk of secondary infections as well as damaged structures interfering with the functioning of essential systems like the gills. That your shrimp isn't eating is certainly grounds for concern. Medical treatment of crustaceans is basically non-existent as far as the hobbyist goes, so this really is a case of "wait and see". Provide the right diet and optimal water conditions and see what happens. Definitely keep her away from any animals that might attack her or otherwise express unhealthy interest -- other shrimps, territorial cichlids, nippy tetras, etc. Cheers, Neale>

Internal Parasites... In ghost shrimp... possible???   2/6/08
Hello crew!
I'm back with another question... sorry...
So today I went to my LFS and picked up about 20 ghost shrimp with hopes of keeping them in a tank and possibly breeding for my GSP to munch on...
Well I was looking in the bag before I dumped them in the net I noticed a long stringy thing... pure white... by long I mean about 4.5" and upon further inspection two of the shrimp themselves had these things INSIDE of them... what are they and should I be worried? The tank itself is fully cycled and running at tip top shape and I kept the 2 infected ones out in a separate 1 gallon tank for observation...
Thanks!
Jess
<Hello Jessica. Without seeing the "long white things" it's difficult to say what they are, but they certainly sound like could be tapeworms or something similar. Shrimps are of course transparent, and they have a digestive tract (the "vein") running along the dorsal surface (the back) of the animal. Depending on what the shrimp has been eating, this can be a variety of colours. Obviously, this isn't harmful. Tapeworms are segmented and very flat, while nematodes, the other possibility, tend to be smooth, cylindrical, and with obviously tapered or pointed ends. In any case, I wouldn't use the infected shrimps to feed your puffers; at least, not raw. Boiling should kill the parasites (if that's what they are). Cheers, Neale.>

Ghost shrimp, horsehair worms.... -02/06/08
Heya Bobster (and Neale, and all),
<Howzit Sab?>
Regarding "Internal Parasites... In ghost shrimp...
possible??? 2/6/08", the answer is most assuredly YES, it's possible. The animals Jessica saw, the "long white things", are almost certainly horsehair worms. These strange critters affect crustaceans and insects; to my limited understanding they do not often affect fish. Apparently larvae can bore into most any aquatic animal and encyst, but that's it. And you need both a male *and* female worm to make eggs.... I would only be slightly concerned for a fish that consumes a parasitized shrimp; in the following link are videos of the worms exiting animals that have consumed parasitized hosts of these worms (not for the faint of heart):
http://www.nature.com/nature/journal/v440/n7085/suppinfo/440756a.html
<Ahh!>
I have seen more than a hearty handful of ghost shrimp with these bizarre parasites. Often you can see the worm moving about within the host.... Freaky, freaky, freaky. In my experience, about 50% of the shrimp with these worms died when the worms left the host, and thereafter, did not have a great survival rate. I *have* had shrimp survive after the worms exited, but not a great many.
The worms can leave the water on their own - I've seen it happen - but I assume they die quickly if they do so. All the same, I wouldn't put a container or tank with parasitized shrimp next to or near tanks with healthy shrimp or even pet or feeder insects.

Attack of the Killer Cabomba? - 08/22/2004
My sister put a plant called Cabomba caroliniana in her aquarium and within hours the shrimps she had died.
<Pure coincidence, unless the plants had some sort of toxin spread on them....>
Does anyone know if this type of plant is injurious to shrimps?
<It is not, not at all.  I have had plenty of shrimp in aquaria containing this species of plant.  Did your sister use any sort of a dip for the plants before adding them?  Some people will dip plants in solutions to kill snails, etc., and if not rinsed *thoroughly*, I imagine some of the water from the dip would get in the tank, and possibly cause harm.  Otherwise, I assume this is pure coincidence.  If you wish to explore other reasons for the shrimps' deaths, please respond with great detail on your tank - what size tank?  How many and what kind of shrimp?  How many and what kind of fish?  What do you feed the animals?  How often do you change water?  What other maintenance do you do?  Do you add any chemicals to the water (aquarium plant fertilizers, iodine for the shrimp, etc.)?  What are your readings for ammonia, nitrite, nitrate, and pH?  When was the most recent animal added to the tank, and what was it?  Hoping to help you get to the bottom of this,  -Sabrina>

Ich medication is not working
Hello there, I am having a problem treating ich in my tank.
I have a 29 gallon freshwater tank. I have a few hatchet fish, and some black phantom tetras (I did have cardinal tetras, but they all died)
<A tough fish to keep, indeed; very, very sensitive to medications and water parameters.>
The hatchet fish were the first to show symptoms.  I also have a wood shrimp, which I took out before adding any medication.
<Ahh, good move!>
First I got Kordon RidIch, I have been using this for over a week and it does not seem to be doing anything.
<It may take a while for the meds to become effective, especially if you are using it half-strength (recommended with sensitive tetras, etc.).>
After I started using it, I noticed that the black phantoms started to get spots, it looks like the hatchet fish have more ich now than when I started.  
<It may appear to get worse before it gets better.  I would strongly recommend reading the following article for a better understanding of this illness:  http://www.wetwebmedia.com/FWSubWebIndex/fwich.htm >
I have been following the directions, and doing a water change before each treatment.  
<Wonderful.>
I went to the pet store today and bought some Mardel CopperSafe, it doesn't give me very much information about it. I also read some where that if I use copper in my aquarium, I won't be able to put any invertebrates in the tank, and I would like to put my wood shrimp back in.
<You are *exactly* correct!  Copper will adhere to your substrate, decor, etc., and leach out slowly over time.  Returning the shrimp to the tank after copper treatment is very, very risky - I would not use the copper, at all.  Ananda introduced me to a product called "Eco-Librium FW" made by Fish-Vet; she has informed me that it works very, very well, and has thus far been safe for her scaleless buds - but I do not know how shrimp-safe it would be; no ingredients are listed.  Here is the manufacturer's rundown:  http://www.fishvet.com/pages/disease2.tmpl?sku=09202001140509 .>
Do you have any suggestions?
<By far, your best option is to remove the fish from the tank and use whatever medication you prefer on the fish in a separate quarantine/hospital tank.  Then, you will not have to worry about the shrimp, and he can go back to his home after you clean the RidIch from the tank.>
Thank you so much,
<Any time.>

<Wishing you well,  -Sabrina>

Molting, Dead, or a Shell?
Ok, I've had this bamboo shrimp for several months and when I woke up yesterday it wasn't moving.
<Yikes, sorry to hear it!>
Well, I know a dead/ sick/ injured fish when I see one but I don't have much to go on when it comes to shrimp. Its legs are still spread out as if he's about to start walking and yet there he stays not moving any appendage at all.
<Do check that this isn't an empty shell - I have been fooled a few times by shells left over from molting.>
Well, the shrimp and other crustaceans I've seen curl their legs inward as life ceases but those are usually served with cocktail sauce. So, not wanting him to be dead I convinced myself that he is/ was merely molting therefore I should leave him be.
<It should be fine to remove the shrimp/shell.  If the shell is empty, your shrimp is probably lurking around somewhere in there.  If it turns out to be a shrimp, well, my apologies. :( >
However, if he is dead I don't really want him to decay in my tank.
<Agreed.>
How long should I wait before removing the body (exoskeleton or carcass) from the tank?
<Go ahead and remove it.  My shrimps usually devour their shells before I get to them, so I've given up trying to pull them out.  If the shell/shrimp is still in there, and still not, well, alive, go ahead and pull it out.  I'd also like to mention, adding iodine to the tank will help your inverts out tremendously.  I use Kent Marine iodine in my freshwater shrimp tanks, at a rate of one drop per ten gallons every week.  Since doing this, I have experienced tremendous results with my shrimps.  I do wish you and your fan-handed pal the best!  -Sabrina>

Shrimps, FW
Hi there
    I got a 5gal. tank for Christmas last year.  It brought back memories of my childhood almost 50 years ago. I quickly went  down to a local fist store and to my amazement found a $.79 tank (just before  the store owner would get new fish on Thu. he would go threw the tanks and any single fish he would put in this tank just to get rid of them.) I was like a kid  again every few weeks going down to the store and seeing what was there. I have  3 neon's, 3 white clouds, 3 zebras, and a white vial tetra in the tank.  few  weeks ago I got 3 ghost shrimp but they seemed to die during there mullet.
<?>
I  went down and bought 3 more and again they seem to be dead one at a time on the  bottom of the tank. I went out and got Kent's Iodine the label said 1 drop per 50  gal. so took a cap full and cut it with 10 caps of water. I add 1 drop per.  week with my gal water change. And of course went out and got (yes you guessed  it ) 3 more shrimp. 1 seemed to die but I lost the other 2.
<?>
My tank is pretty  heavily planted with Java moss and ferns, swords plants, and several other types  of plants I got from the fish store. I really like the different shapes and  colors of the plants with the fish swimming around them but my real joy is the shrimp. I just got 2 bamboo shrimp but 1 is a fan feeder about 1.5 inches  in length (I think you call it that) and the other is a long armed shrimp about  2 .5 inches in length. They were in the same tank about 5gal with about 12  other shrimp of the same types. After I put them in my than I noticed at least 4 ghost shrimp come from some place to investigate the newcomers everyone seems to be getting alone wonderfully.
    Now to cut to the chase am I adding  the right amount of iodine to the water or should I just add 1 drop per gal. as  you said in the past?
<Not able to tell w/o testing... this material is transient depending on water chemistry, bio-load...>
    Should I buy shrimp pellets for the  bamboo shrimp or is my testament and live plants OK?
<Please read on the Net re... not able to live on pellets>
        What is the  best way I could care for OTTO & HERMAN they are so cool?
<Who are they?>
I really think my tank is perfect until I get a bigger tank  with more plants and shrimp.
    Is there any types of shrimp or  invertebrate I should stay away from in the future?
Thank you so very much for your time and please keep up the  good work Walter.
<Walt... please read over, have someone there review your writing before you send it... Some doesn't make sense, a bunch is mis-spelled. I do wish our "shrimp queen" were with us more often (Sabrina). Will cc her here in the hopes she will respond. Bob Fenner>

Missing Shrimp
I am the proud owner of a new 20 gallon freshwater aquarium. I have had it up and running for about 2.5 weeks with two scissortail Rasboras, and it is now completely cycled. The ammonia is 0, as is the nitrite level, and the ph is somewhere around 7.8. After weeks of anticipation, I went out today and bought two Gouramis that fade from orange to silver, three cherry barbs, a false Cory, and two japonica shrimp. If you haven't heard of them they were about an inch long, and looked like ghost shrimp (the store said they cost more for their "algae eating abilities"). 
When I returned home I excitedly acclimated them and then released them into my aquarium, I came back about an hour later, and the shrimp were gone, I had heard somewhere that some shrimp burrow and I was hopeful, but it is now the evening and there is still no sign of them. Were they eaten by the Rasboras (2.5") I hope not. I was also wondering if you have any suggestions for a peaceful community fish that is blue or green, I feel like there is so much red in my aquarium. And one last question, I also have a ten gallon aquarium with a golden mystery snail, one albino Cory, I adult male guppy and two adult females, 5 juveniles, and about fifteen on week olds. What should I do to relive my overpopulated tank, my nitrite and ammonia levels are zero but I can't help but feel that they are crowded. Thanks for having such a great site,

<First, keep testing for ammonia and nitrite. Two and a half weeks seems a little quick to establish good strong bio filtration. And you stocked a little quickly. The new fish add to the amount of ammonia that needs to be filtered by the bacteria in your filter. The colony will need time to grow and adjust. Do water changes to correct any spikes. When ammonia and nitrite stay at zero AND nitrates are on the rise, you are cycled. Not sure what happened to your shrimp. They may be hiding in there somewhere. They may have been eaten. Not sure what a "False Cory" is, but my catfish love shrimp. You may also want to check in your filter. Don> 

QUARANTINE FISH TO SAVE SHRIMP
Hello! Just a quick question about my dear little Bamboo/wood/Singapore shrimp... I was unaware that these little guys could jump so well! I had a problem with a parasite on some of my other tropicals - Blue and Dwarf Gouramis and a couple stray fruit tetras, plus three Pictus Cats. The cats brought some sort of white parasite in with them.. much smaller than any ick I've seen, more like dust. I'm thinking (and treating for) fish lice, but the meds I have cover the bases for gill flukes etc as well. Any thoughts?  Anyhow, he needed to be separated since the meds said NOT FOR USE ON INVERTEBRATES on them. I had him in my hospital tank, just a 2g with a small filter/airstone and heater, but I left the lid off. Hearing a noise, I discovered he was GONE. I found him, about 5 minutes later, on the carpet. Will this kill him? Anything I can do to help him? He seems shocked. Well, any input appreciated! Thanks a million!

< Most aquatic arthropods can handle some terrestrial time as long as the gills are not allowed to dry out too much. Your problem stems from not quarantining your new fish prior to placing them in your main tank with the shrimp. Many medications can harm and even kill shrimp so treat your new fish in a hospital or quarantine tank to keep your invertebrates alive and well in the regular tank.-Chuck>
