Sorry if this has been asked before, but as the title says, can I add a Synspilum in with my IT's? Other tankmates would be a severum, florida spotted gar, and a few bichrs. All living in a 180 with 50 sump. How aggressive are they? All ive read suggests they are peaceful (for a cichlid). Also is it possible to sex them at 4 inches? Id prefer a male for the coloration... Thanks guys
