dwarf cray question

Crays will eat anything they can sneak up on and catch. Frogs are usually at the bottom, that's like asking for a cray to eat it.
 
the cray even though dwarf, will catch and eat other tank mates if given the oppertunity.
 
Mine have never attacked another tankmate, though one did clip an oto once when it tried to reach for a pellet.
