i don't know if you made a decision or not, but you may look into the feeding plan you have there. fish are high in fat and i'm not sure how much chitin is in shrimp exoskeleton. i know for frogs, fish are a treat, not a staple. and we avoid meal worms and the like because of the chitin in their exoskeleton. can cause impaction and most likely death. i would suggest on doing some heavy research on any amphibs you decide to go with .
