typical of clawed frogs, although ironically I tried mixing my ACF (which wasn't that small) with cichlids, and everything was fine for months until one day the Crenicichla sp. Venezuela decided to rip of every limb from the frog...leaving only a torso. I ended up having to re-home the pike to another MFK'er after it did away with a beautiful Dimidochromis kiwinge I had.
