Sorry to be following your posts man, but you need to give ppl some more info here. What is the tank size and stock exactly? You asked on earlier threads what would happen if you put a jd with your flowerhorn, ppl responded that it would be bad, so instead you bought 2 smaller gt's. I am sorry to sound like a dick, but does that make any sense?
If it has bite marks, take the fish out. Get some meds or at least let him heal. I dont even know what to say since you wouldnt respond to any of my questions before. But get that fish out, why out a fish thru that for no reason, or return the FH so you can have more than one fish if you only have one tank. Damn
