Getting A Fry-Eater

[BettaLover101]

Hi everybody ^_^ Not sure if any of you remember, it's been so long since I've actually posted anything. In any case, I'm looking for a fish, something that can live in a 20 gallon or smaller for it's whole life. Also, it has to be willing to eat any fry that I need to cull. So, what do you think I should get?

How big are these fry?
Kribensis cichlid? Or another small cichlid.

Just betta and guppy fry, nothing big.
I'd like some sort of fish that I could keep solitary if at all possible.

Kribensis could live alone, though the tank may feel empty.
A male convict cichlid may actually be a better idea, bigger, could handle more fry. A male would be perfectly fine in a 20 by himself. Just be sure to give him a cave.

Jeweled cichlids can live in a 10 gallon tank solo... I believe they get big enough to eat small fry....

Thanks. ^_^ I'm liking the idea of the Jewel Cichlid since it is so vibrant.
Is there anything else that could work in a 10 or 20 gallon?

Pretty sure you'll only get that nice colour with a breeding pair.
And, no, not that I can think of. Really limited to smaller cichlids. Unless you want a Molly as a fry eater.

Yeah, Mollys will eat fry for sure. Or a giant betta.
