Angelfish - Swimbladder?

[ddowling01]

Hi,

One of my Angelfish was badly "beaten up" a couple of days ago. I had two tinfoil barbs who got too boisterous so they have now been moved out into another tank.

His fins are badly nipped and he has a red sore mark on his side.

He has been swimming on his side and tries to swim, but just floats to the top and lays on his side.

He is breathing normally, but not eating anything.

What are his chances of making it? I really would rather not kill him unless he is suffering.

Tank is 300L, tank has been running for over a year with no problems. There is only about 6 fish in the aquarium. Others are eating and swimming as normal. 20% water change done twice weekly

Tank size: 300L
pH: 7
ammonia: 0
nitrite:0
nitrate: 20
kH: Unknown (hard water)
gH:
tank temp: 27c

I would put him in a tank by himself, no lights and treat with Melafix and Pimafix. I've had fish that looked like they were dying saved by a stay and treatment in my hospital tank. Since then I never kill fish and give them a chance.
