Stanzzz7 I know is said I didn't want to discuss this as we have debated this out on other threads... but I will mention one point. The fish that killed and terrorised more fish than anything I have ever owned was a 11 inch atabapo red pile cichlid, also known to be aggressive but kept in cichlid comm tanks the world over, so should this fish NEVER be comm'ed because I can be a killer? I raise it as isn't most large fish community aquariums 'walking across a road blindfolded' until something happens? This forum is resplendent with people who have killer cichlids in comm tanks etc....
You make a valid point.
Some cichlid community tanks are just as much of a gamble as what you are trying with the fahaka, can't disagree there.
Personally I have never been a fan of mixed aggressive tanks, they are rarely ever successful long term.
Most people that have had "success" don't normally mention the poor underdog cichlids that got batterd and left clinging onto life in the top corner of the tank.
I answer lots of post regarding cichlid compatibility. Where most people say,yes it could work,I normally advise against it.
Cichlids can be trial and error and mistakes do get made but we can also use a little common sense with the most notorious of aggressive or strongly territorial of cichlids.
Dovii,red tiger motaguense, Trimac,umbees,and certain pike cichlids are just a few that I have advised against trying to build a community around.
Often the tanks are too small to meet each species territorial needs.To my way of thinking its best to look at more peaceful fish if a community is desired, unless the tank being used is big enough to cater for each species need for space.
In not trying to be argumentative I just feel a little compassion for all these fish that get bullied to death. I also feel there maybe a lot of young or inexperienced keepers viewing these posts and I feel it's right to point out the pitfalls rather than say,go ahead it could work.
Just trying to save headaches for the keeper and avoid unnecessary suffering for the fish.
I happen to be a fan of fahaka and yours is a lovely specimen. I would love to have one but can't bring myself to devote a tank to one fish. Therefore I choose something else.
