Number four on our list is the ever so famous crayfish. This species would be much higher on the list if it wasn’t for the chance or a crayfish possibly catching one of your aquarium fish. They are known to just feed on bottom decay but from time to time they will kill a fish.

What makes them so great is the rate at which they feed on their food. They clean a tank bottom a lot faster than the other species. But like I said.. the chance of a crayfish killing a fish does always exist. Their pinching claws also scare aquarium owners a bit as far as picking up and such.

5. Red Tailed Shark
