Just got a new red dragon flowerhorn, he’s about 3.5 inch or so. He just seems a little wired I currently own 2 othe flowerhorns and I don’t get the weird behaviors from them. He is very skittish, sometimes darts around even if I’m not moving. He seems kind of dark in my opinion. And seems to be laboring a little and the occasional “yawn”. I’ve had him for 4 or 5 days now. He’s in a 60 gallon cube by himself. He wouldn’t eat so finally yesterday I broke down and fed him a feeder guppy and he ate it as soon as he saw it, but won’t accept any of the 300 other foods I’ve tried. Floating and sinking pellets, floating sticks, brine shrimp, blood worms, krill. Nothing seems to entice him, he also seems kind of green in the face is this a problem? Or just his coloration?
