They are fish about the size of a large Guppy that eats baby guppies and resemble a piranha. In Adventure Mode, they drop diamonds that are worth $200 and can be bought for $1000 in Tank 1 and 4. Like all fish, they will die if they are starving too long. In Virtual Tank, they cost 100 shells and 1000 for a colored Carnivore. They drop blue conches worth 5 shells.
