Oh ya i know, they all live in seperate enclosers

Ok because from this picture it doesn't look good.
Picture 3 of 8 from African bullfrogs

Considering the feeding drive these frogs have, I would not feed them in the same enclosure as well. In a feeding frenzy the larger frog might go for the smaller one instead of the feeders.
