Itungi lethrinops dying right now, HELP!!
I do not know what caused him to be so stressed out, the other lethrinops in the tank are doing fine. Water parameters are PERFECT! He started at the top of the tank, hiding in the corner, then he sank to the bottom. He was able to swim around some, but kept sinking to the bottom. I placed him in a cave so he could be in a safe dark place to try to calm down. Eventually he swam out, and I though great he's feeling better, but then lay on the bottom, and started going sideways, breathing heavily. I think it's a swim bladder issue, but I don't want it to be. I placed him back in the cave, and turned the lights off. From what I can see he is lying on the bottom of the cave, breathing heavily.
I added prime, and melafix hoping to distress him a little bit. Anything you can think of? I don't want him to die!
