OK I know that it is in the family of managuense and dovii and I know it is a piscavore but i wanna know more about this fish like how to tell between male and female and how big they get and PH prefrence. I bought him at my local pet shop and He is about 4.5" now he does great with my 2 managuense and my wolf cichlid, ( by great I mean they lip lock alot nothing to serious though they are all in a 150 tank) if anyone can help that would be great. its the first time ever dealing with this fish.
