I have 3 new cichla kelberi and they are very aggressive with eachother or at least one of the most truly aggresive cichlids I’ve ever kept and one of them is extra extra aggressive and so I put 2 Oscars and catfish in to calm the aggression and it’s worked slightly and gotten better but still very aggresive any idea how to help? The tank is 90 gallons with an fx6 usually at 82 degress just because they are new to the tank.
What size Are they mate??. If they are Still Small..., [I know that this Method is Downright UGLY] , but, Personally, On Many Occasions...,{After I have Spawned MANY Cichla variants}, and The Act of Cannibalism by the many, many Hundreds of Peacock Bass Fry (Especially at The Fingerling Stage) begins Very Quickly too kill each other very Rapidly.
So..., I have found Myself Continuously Using or Packing My Grow Out tanks [Just for a relatively Short Time of their Grow Out and hormones Spurt!!!], with Many, Many brown Onion Bags!!!.
