Obese Or Sick Or Pregnant Zebra Danio

[blackers92]

Ok i have a small group of 5 zebra danio

one of them is massive, like almost 3 times as big as the smallest one.

Hes not long or anything, just like fat

He looks healthy, he's colour is very bright and he is very active, probably leads all the others around.

Im just a bit concerned about his size. I tried to take a decent photo but they never sit still. He would be about 2-3 cms long, from his top fin to the bottom is literally 1 cm, it just looks so out of proportion. Its shape looks completly differnt to the others

I feed them twice daily, along with my yoyos and B/N
they get, tetracolour granules, tetrafin crisps and i put a spirulina tablet in for the B/N

is he just greedy/fat or is he a she and is pregnant.

the link below is a photo, it is fairly bad but it might help you understand its physique

Does look preggers, however i have never bred or looked into danio's, maybe it is just glutteny, how does this fish act, swim normal? eat normally?

well i thought something may have been wrong with it, as it kind of chilled by itself, but in the past two weeks it has gotten massive, it shoals with the other danio, they follow it, or try to chase it sometimes. Sometimes it is agressive towards other danios aswell but I wouldnt say it is agressive at a bad level

i have never really noticed how it eats when i feed them, all the danios swim to the surface when I open my hood, where as my other fish just scavenge
