not to bad
i mean the male can be a pain but he hasn't killed or hurt any of my fish,i even have corys in there
the only fish that really takes a beating is the female but she must like it coz this morning i caught her sneaking up on the male and took a nice shot at his tail lol i named them ike and tina
anyway they seem to practice their ambushing skills alot by hiding in plants and slowly cruising towards a fish and then take a weak strike at it
no harm is ever done as far as i can tell.you should give'em a try
i can't complain this is proly the most peacful cichlid tank i've ever setup.
