I bought 6 male guppies a little over a week ago. They are in a 10 gallon tank that I tried to cycle with Bio Spira with 1 ghost shrimp and 2 baby snails left from the baby GSP's that were in the tank. All guppies were eating except for 1. I'm feeding 2 different varieties of flake food, bloodworms, and frozen brine twice a day. I took back one guppy due to him not eating that I could see for the first 3 days, he was staying at the top of the tank, he looked a little bloated, lost some color on one side and did not seem healthy like the other guppies. Now I have another guppy doing the same thing. I have looked at all the disease pics on a guppy site and can't figure out what the problem is or what to do for him.
Water Tested:
.25 ammonia
0 nitrite
20 nitrate
120 kh
ph 7.8
I did a large water change. I add Prime and aquarium salt to the tap water. He is still the same. Going on day 4 of him not eating. I do not have a Q tank to put him into. The only thing I see different with his appearance is slight bloating, staying at the top of the tank in one place moving his fins and his fins do seem close to his body. I have not seen him go to the bathroom, could he be constipated?
Sick Guppy? Not Eating Bloated

Since this board has been up, we have found there are several questions that routinely get asked in order to help diagnose problems. If you can have that information to begin with in your post, we'll be able to help right away (if we can!) without having to wait for you to post the info we need.
1) Your water parameters - pH, Ammonia, Nitrite, Nitrates and salinity (if appropriate). This is by far the most important information you can provide! Do not answer this with "Fine" "Perfect" "ok", that tells us nothing. We need hard numbers.
2) Tank size and a list of ALL inhabitants. Include algae eaters, plecos, everything. We need to know what you have and how big the tank is.
3) Feeding, water change schedule and a list of all products you are using or have added to the tank (examples: Cycle, Amquel, salt, etc)
4) What changes you've made in the tank in the last week or so. Sometimes its the little things that make all the difference.
5) How long the aquarium has been set up, and how did you cycle it? If you don't know what cycling is read this: Fishless Cycling Article and familiarize yourself with all the information. Yes. All of it.
We want to help, and providing this information will go a LONG way to getting a diagnosis and hopeful cure that much faster.
While you wait for assistance:
One of the easiest and best ways to help your fish feel better is clean water! If you are already on a regular water change schedule (50% weekly is recommended) a good step to making your fish more comfortable while waiting for diagnosis/suggestions is to do a large water change immediately. Feel free to repeat daily or as often as you can, clean water is always a good thing! Use of Amquel or Prime as a dechlor may help with any ammonia or nitrite issues, and is highly recommended.
Note - if you do not normally do large water changes, doing a sudden, large water change could shock your fish by suddenly changing their established water chemistry. Clean water is still your first goal, so in this case, do several smaller (10%) water changes over the next day or two before starting any large ones.

Do you think they could be pregnant? I am not real good with guppies, I am more of the salt water end of things.

Re: Sick Guppy? Not Eating Bloated
All the guppies appear to be male...PetSmart is no help w/ advice. They will take the fish back but will not care for it. They have the same policy as Wal Mart...
I'm going to do daily moderate water changes and add vitamins for now until I know what more to do. I may have to call the vets?

You shouldn't have any ammonias, do a few water changes, and if he looks bloated try feeding him some soft peas with the skin taken off.

Re: Sick Guppy? Not Eating Bloated
Thanks Zombiefetus for the reply.
I'm not doing well with the guppies. Guppies are supposed to be hardy and I'm having more of a problem with them then I did with our new puffers. I have had to take back 3 out of 6 so far due to illness. I have zero ammonia right now. I'm going to do water changes as much as needed until tests check out right.
I have added a bubbler (more oxygen) and vitamins to the tank to help keep a healthy enviroment.

Re: Sick Guppy? Not Eating Bloated
sounds like you're doing everything right. Just keep doing water changes for a few days and see how they do.
I've having some guppy problems myself. :/
I rescued a pair of common guppies from Walmart after they got returned and were going to get flushed, and one of them turned out to be a demon fish. I have them in my community tank, and he's beating up all my other fish (including a mollie and two female bettas), I hate him. I'm thinking of "accidently" throwing him in the GSP tank.
