I thinking of getting a 4inch clownknife. raise him inside my 60 tell his big enough for the 240g. So inside my 60 i have a dozen molly (they keep breeding) 8OTOs, 2TSAE and i think but i might have lost him 2 rosy shrimps.... I might add more smaller fish that will get eaten buy the clown knife to keep him away from my otos and SAE... will this work? SHould i also add a ton of plants? for him to break the line of sight so he doesnt wipe out the hole tank in one night.
