Cichlids are KILLERS !

I have never ever owned a single cichlid, but I bought two at the fish store
because they were on sale. These fish have ripped the tails and dorsal fins
off of my puffer fish, my Cory catfish and anything else in the tank. Before
they kill everything in the tank, I removed them and put them in the
crayfish tank to teach them a lesson and have them chased and bit for a
change. The Cichlid are ruling the crayfish tank. The crayfish are chased
constantly by the Cichlids. If they go near any food or come out for a walk,
these Cichlids attack like it's a life and death match. This is fish is
young and small, what is going to happen if it gets bigger? .. will they
actually kill crayfish? .. are they that vicious? ........
