Can anyone tell me why one of my male guppies has a bloated stomach. He's not really swimming sound as much as he usually does. The only thing I can think of is that one of the females gave birth and he ate to much of them but it seems unlikely. Help??
Could be constipation you could try the pea trick....cook a pea, take the outer shell off...smash the pea a bit and try to get the guppy to eat it....it works like a laxative.
If he isn't constipated it could be Bacterial infection.
How many fish are in the tank? what size tank? what are the water parameters? (Ammonia Nitrite Nitrate)
What foods do you use? do you use freeze dried a lot?
How does his scales look? are they sticking outward? has his color faded?
I don't know.....could have been infection. Just keep a watchful eye on the others....i had the same problem with a couple of my guppies...bellies got bloated and found them dead later on......I know guppies can be very problematic from what i understand they are widely inbred and can have loads of issues and usually after the first generation of babies comes along most of the problems go away with that 1st gen. (once you get new DNA in the strain)
