Question regarding overeating.

[pho3nlx]

No, I didn't overfeed my fish He did that himself.

I thought I had researched enough and learned enough that I could tackle most problems that present themselves, but this is one that I wasn't prepared for.

I know that most fish will chase fry. However, I have a Killifish (relatively peaceful, leaves everyone alone) with a few mollies (harass each other, but not "seriously"). One of them gave birth to an undermined amount of fry. I wasn't there to witness it, nor did I put her in a separate tank, I have a fry tank with a bunch of mollies already, and didn't want to care for several more. So I figured, some of the fry will get eaten by the killi or the mollies themselves. What I didn't account for... The mollies didn't touch the fry. The killifish ate ANY AND ALL he could chase and catch, and only him... I pulled 6 fry out because I didn't want him to keep feeding. Suffice to say, his belly is HUGE. I imagine he must've eaten somewhere along the lines of 15-20 fry. Is he in serious trouble for eating this many?

Thanks.

I had a betta in my livebearer tank and one of my female guppies that produces about 70 fry a pop hatched when i wasn't home. There was only four fry left when i got home and the betta was so fat he was just laying there on the gravel. I dont know if he died because he drowned or if all his organs were jammed together from his stomach being half of his size so he might be in serious trouble.
RIP fat betta

You have to regulate the supply of foods. Several species are opportunistic eaters. He may not be in danger of digestive problems yet but it is best not to leave the mollies to breed on their own or you'll see the killifish become more bloated. Adult mollies will never cannibalize their fry that easily. I've always noticed this unless you refuse to feed them for a few days in which case they will resort to eating the fry to satisfy their appetite.

Well, his belly seems to be going down, and I moved him to another one of my tanks with fish that aren't producing fry any time soon.
