i have had alot of problems with my tank lately (my fault i know better then to mix so many cichlids)but just now looking in my 80g tank 4in redhead,two 4in flowerhorns,4in blackbelt,convicts pair,catfish,pleco,green terror,two bichirs,two firemouths.two frontosa, and gold severum. the last five are on the way out but the gold severum one of my favorites is suddenly missing chunks of fins just lost a african cichlid but thought gold severum was the least of my worries.is the blackbelt that aggresive of a cichlid? *** heard him mentioned in the same breath as red terrors and red devils.Is ther a way to keep the severum would a oscar or green severum help?Does the blackbelt need a species only tank?
