Hello!!!
I have just yesterday put in to my cycled tank 6 zebra danios. They have all been fine, until now, I think...
One of them has started 'hanging out' in one corner, around 2 inches from the top and doesn't seem to want to play with the others...
As this is my first tank (although I have some experience with fish, and worked for a company maintaining fish tanks around london)
I am a little nervous and of course would like all my fish to be happy and healthy... I was wondering if this is normal zebra danio behavior, and whether or not any of you have observed similar things in your own experience.
This particular fish is the smallest out of the group of 6, and he/she does seem to have a bit of a funny shape on its underbelly... Wavy, would be the best word to describe it. All the other fish seem fine, so I don't think it's nitrite poisoning, or at least I hope that it isn't. Perhaps he's just a little nervous as it's a new home for him/her?
Anybody? I'm pulling my hair out here!!! :-[
Thanks,
felix

Is the tummy a little plump, maybe bloat? Look through the sticky in the disease section to see if you can find any info there. How are your test stats ammonia, nitrite, nitrate, how large is the tank, are these the only fish. Hopefully we can figure out what is wrong if anything is wrong, it's possible he's just new to his home.

WELCOME TO FISHLORE, you'l find a lot of help and friendly people here.

Thankyou!! I'm gald to have become a part of the community!
The tank is 16 gallons, I cycled it for two weeks before putting anything in, on the advice of my former boss in london.
I put in 6 zebra danios and two ghost shrimp for now... I'm ashamed to say that I don't have a testing kit, so I can't tell you exactly what the levels are, although, i'm starting to think I want to get one.
I will check out the sticky section now...
He/she does seem to have a minor swelling on its belly region... I can't say I know the names of all the fins, but it's directly under the first fins going back from the head. (I know I sound like a doofus! woops!) It's "arm fins"? D'oh!

The problem is that your tank is probably not fully cycled, though zebra danios should be able to survive the cycle as they are hardy fish. Read the nitrogen sticky at the top in this board and when was the last time you did a water change?

I haven't done any water changes whilst ive been cycling the tank... I thought that because I hadn't put any fish in there until the two weeks were up it would speed up the process if I didn't dilute the water... I hope I haven't had a major mishap in this respect... :-\ :'(
I have just now purchased a testing kit online...
Also, not wanting to be pedantic, but what is this 'sticky' you refer to? I can't find it!
Thanks alot, I appreciate your help!

just to clarify: I haven't done any water changes yet since I set up the tank, and planned on doing it a week after I introduced the new fish.
thanks

ok, ive read up on the cycling process... I did drop in some flake food to start up the cycle, but most definitely not every 12 hours...
I think you may be correct... the cycling may not have finished... Much to my dismay, as I don't want the poor little guys to be exposed to all of that nastiness... I'll keep an eye on them, naturally (hard not to! so lovely to watch!)

You should probably do a 10% water change... it's hard to tell how much though since you don't have any tests to see what your ammonia and such are at.
Maybe a bigger water change is needed... *shrugs* I'm sure someone more knowledgable than myself will be able to help ya more.
