VRWC: Thanks for the comments! I really miss the guy. Had a few since, but with a few dovii and other Parachromis it just became redundant. Grammies and dovii are definitely my faves of the piscivores -- interesting how they're so similar in every way except size! If I had to pick, it's tough to go against the littler guys!
Doviikid: They definitely seem to be combative with fish that will resist them back, but I've always had great success keeping them with the less aggressive types (like the rostratus in the pic above). Anything similar (i.e. Parachromis species) is a definite no-no. Until recently, I had a pair in my outdoor pond/tank that coexisted with just about any kind of cichlid you could think of...but that's a huge tank. If I had to choose an ideal setup, I'd try to get a pair (starting with a dozen or so) mixed with two or three pairs of cons or neets and a bunch of dithers (though they often end up dead in less than a huge tank). Perhaps some unrelated fish that wouldn't challenge anyone like some of the calmer Viejas or Astatheros species could be added. As you can see in the pics above, they will respond to aggression in kind but otherwise ignore anything that isn't "food!"
