My N.Venustus is one mean cichlid with the other fish in the tank....

I think these are aggressive for African Cichlids, but I've kept both (adults & breeders) together with a grow-out Amphilophus amarillo, and when this bad boy finally grew up (7-8 inches) it was made awfully clear who the boss was...then after 6 months he decided to filet all the males left in the tank.

The crabros and the venustus stood no chance...he also decided he didn't like the way the 10+ inch Pearsei male looked and re-arranged his face too...three more for the dead fish thread.

Tongue's housing the amarillo currently...we'll see how long that lasts, I'm having sellers remorse (er uh, givers remorse I guess).
 
3-4in. rio blanco red tiger mota. hands down the meanest fish i've had. i have had this fish seperated from the other two with a divider because he wouldnt let them eat. the divider is siliconed in place and sticks out of the top of the water a half inch, come home tonight and he is on the other side with, you guessed it murdered tankmates. 2in. mota and 5 in. silver aro. i dont know whether i should love this fish for what he is, or hate him for what he's done. gorgeous fish though.

I have a 13inch male dovii that is crazy. You put the net in the tank and he attacks like a rocket. I can't even put my hands in the tank. The alge is getting bad, but he tries to bite everytime your hands are in the water, and he has big teeth. Also he jumps at the glass tops all day long, throwing water all over my floors. Actually that habit of his is getting really annoying.
 
Male dovii and male trimac run a close race for me.
