I've been trying to find a fish I can put in with my guppy fry to eat the left over foods.
I know they can grow quite large and I do not intent to keep it in the 10gallon forever. It can be moved to a 20 with the adult guppies and then(come spring) moved out to a pond that I'm setting up out back.
My questions are how fast they grow? If I bought a 'small' one, how long could I keep it in the ten/twenty gallons inside before moving it outside into the pond?
I have a few algae wafers to supplement it's diet, but do they really eat the left over food that reaches the bottom?
Should I buy more than one,or are they fine being the only one of their kind?
How worried should I be about them eating the fry? Will they actively hunt them or only if they're starving? Again, I'll be buying a small one so this really depends on how fast they grow I suppose since the ones I saw looked too small to eat any of the fry while they're alive.
I keep my fry tank at 78-ish degrees, is this too high a temp?
