Is my neon tetra pregnant or sick?

I've had a small school of 4 neons and have been living in a discuss tank75 gal. for a month or two. They previously were in a 30 gal. community tank for a long time. One of the neons has a big underbelly and is deffinately not natural. I moved it to a 2 gal. tank, by itself. I have no Idea what to do. I've heard of some diseases that cause a big underbelly and its actually killed one of my black mollies in the 30 gal. tank about 4 months ago. Theres no disease in the tank or sick fish, and there never has been. please help!

here's some pictures, it doesn't really look like it is that the belly is that big in the picture but I assure you its fairly big

 

HI it does look pregnant ,but I read some where that it is difficult to breed them at home so maybe you should treat it as a disease. :-\

 

I think breeding them is difficult because they tend to eat their eggs and therefor none hatch... I'm not sure If she is pregnant though, You could try raising your temp a bit and then treating for intestinal disease but honestly ive never seen a pregnant neon.

 

If it were pregnant what should I do? what temp., feeding and things like that. I it does lay eggs, how would I know so I could sepparate it so it doesn't eat them.
any suggestions?

 

I hope I'm not too late my advice..I lost a school of six Neons because one of them had exactly the same swollen stomach and I took too long to separate them..I even posted a thread asking pretty much the same questions you're asking in yours in the Freshwater Beginners section..turns out she was sick,and my procrastinating cost me the entire school..my advice?..put her in a quarantine tank a.s.a.p. ...assuming the worst hasn't already happened!

 

Good advice Richard... but might I add to anyone when in doubt never wait go the quarantine route straight away if you have the tank to do it.

 

Would this effect other fish as well? Once in the quarantine tank, what should I medicate it with?

 

HI there,

I sit with the same problem and glad to see that I'm not allone!

My gourami's mated a while ago but how do you know what's eggs and what's bubbles?

I might just sepperate her but have no spear tank?
So what now?
