The red devil that I had was very aggressive and ate feeder fish like guppies and the small gold fish. It also tried to take a bite out of my finger while I was cleaning the tank.
Red cichlids I am assuming as red devil cichlids and in which case at least a 75 gallon as they get upwards of 13 inches. Also, additional fish in the tank would diminish any aggressive behavior so they would not be focused on one another.
no because the bigger cichlids will eat the little cichlids.
No they can not.
I suggest no, because I personally own a red devil cichlid. Known for their extremely intelligent and aggressive behavior, one red devil should have a 50 gallon tank all to its own. My personal experiences show that a red devil is able to kill all sorts of cichlids, some being even larger than itself.
red parrotfish? Well the reef species eats live coral, and the red parrot cichlids eat regular cichlid fish food. You're question is too vague.
I caught one with a medium size red devil. Try that !
I have a 260 L tank and have to rainbow sharks with 12 assorted cichlids and have not had any issues.
ok u need to eat a apple
Anything carnivorous and big enough will eat them. Think Oscar.
In the wild, African Cichlids eat plants like blue-green algae and organic detritus. These plants are high in fiber, but provide little nutritional content, so cichlids eat continuously to maintain their metabolism.
It is expected that Jewel Cichlids with Convict Cichlids.
No my red devil is stronger than yours.
