Hey that's cool Sorrell! I have a friend who has frogs, she talks about how they grab fish bigger than they are and use their "hands" to try to stuff it down their throat!
I think I value my fish too much to have one of those, It would be my luck the thing would jump from tank to tank while I was at work and I would come home to one fat happy frog. I worry enough the way it is with my crayfish. He's in a tank by himself, but I keep the water level down just a bit anyway just in case.
