So I’ve have a snakehead (Channa quinquefasciata) and a pair of Jags. The snakehead is mostly at the bottom hiding in his cave. The jags are usually in the middle or at the lower half. I wanted to add a top dwelling predator in there. I don’t want to add an Aro or agar cause they get huge. So I’m probably looking for something that won’t cross 14 inch and usually stay at the top, is a predator and all be compatible with it’s tank mates
