Most aggressive feeder?

I did them with bettas a while ago, as long as they're in a small enough tank and there's nothing that's gonna get to food much/any quicker than them, they will do fine IME.

Oh yeah, I was talking about axo's

don't forget the heater....small enough tank....but big enough for a heater.

True that. I used tiny ones all the time, plus a little sponge filter for like $3 from amazon. A full 10 gallon setup might cost (minus tank and stock) $50 all new on Amazon, even less.
