Fat Male Guppy

[Fazzius_maximus]

I'm really worried about one of my male guppies, if I didn't know he was male I'd swear he was pregnant. He's one of 5 guppies in my tank, all male and all (except him) are absolutely fine. I've left him 2 days and have just kept an eye on him but he's even bigger today!? Any advise welcome

PS He's swimming and eating fine

are his scales raised/sticking out any? tanks size/stocking/water stats?

His scales are fine, and he's not swimming any differently. The tank is a 25 litre, the temp is around 26/7 and all the chemical levels seem fine. None of my other fish seem to be having any problems at all. Any ideas?

 

[lilfishie]

has he been going to the loo? and what are your ammonia?nitrite?nitate? results

I had my male guppies do similar to this just before they died.

Where is the swelling, just in the abdomen, or under it's chin if you like. Mine went very chesty (for want of a better word) in appearance shortly before the last of them died.

Good luck, but i hope it's just indigestion, try feeding them shelled peas!
