Dead fish woes

palvyre · Sep 15, 2013

My Emperor is harassing my other fish and he has managed to kill 3 of them. My CBB, Naso Streamer Tang, and Dragon Goby all toast. No signs of any disease. All fish were at healthy weight, started hiding toward the top of the tank, breathing heavy and then toast. Going to try and sell the Emperor back to AC I guess before he kills any of my other fish.

You actually see him going after the other fish? Was he in first and then the others added?

"My Emperor is harassing my other fish and he has managed to kill 3 of them. " Did you see any marks on these dead fish? Fins Nipped real bad? red rash marks? If you didn't then that might not be your problem.

Some frayed fins, and he is always grunting at them.

Even though there may not have been many red marks or freight Benz the constant attacks by an aggressive fish can cause stress on the other fish and thus leading to their death. It could be that they stopped eating as much is a used to because of this aggression or just simple stress on the fish and I get an infection. How big is this angel fish?

Angel is about 6". The Naso Tang was 7". I inspected him after he died and I didn't see any sign of disease.

I have even checked the tank for stray voltage. All readings at 0. The only other thing I see is a very large Aiptasia. I don't know if that could do this.

doubtful on the aptasia... you would also see a red mark. you have a 180 right?

FWIW, I have seen some angels turn in to real bullies. I had a little yellow tail pygmy who was a real butthead. Chased fish 3x his size. hated new additions. always picked at them longer than a tang would. then one day.. he was mysteriously gone. Never found the body. I think the other fish hired a mobster fish or something to dispose of him.

Before the heavy breathing I added microbe lift special blend, I wouldn't think that would pull all the oxygen out though given the other fish appeared fine. The top of my aquarium is open as well.
