Zebra Danios Becoming Very Fat

[t4ppo]

Hi, i have 5 Zebra danios in my community tank, And just recently the last couple of days 3 of them have become Extremely fat! Only 3 of them though, and they all seem to eat the same, Today i have noticed it more because they are bulging out at the bottom today on there bellies,

Is there something wrong with them?
Also the fins on the biggest one are sticking out they look bigger than normal,

Thanks.

could either be a bacterial infection or they're constipated - have you tried them with peas yet? Mine gobbled theirs up then turned into poo machines for the next few hours . Are there any other signs out of the ordinary?

those 3 could also be females a few of my females do this every month or so basically means they're getting ready to lay egg's ...I've never managed to find any of the eggs yet !
