I just woke up this morning and 1st thing i do is check my tank and feed my fish. I noticed my 6" clown loach stuck in a small ornament i have in my tank for my smaller fish. He usually hangs out in his large castle and only comes out to eat and comes out at night when the lights off. not sure why he thought he could fit through this small hole. His head was out of the ornament and his mid section was stuck. There was a cloudy slime coming from his body and covering the ornament. I put my hand in there and pushed him backwards and he then got out and flew back to his castle. My concern is that where he was stuck there is no color on his body . Looks like a white circle going around his mid section right where he was stuck. He is breathing rapidly also, but seems to be doing fine other than that. Should i put any medicine in the water to help him heal or let him be. I have Melifix on hand. My other fish i have are 4 calico fantails,4black moores, 1 clown loach,2 plecos,2 bottom feeders(not sure what there called), 2 large angel fish,2 tiger barbs,1 black tetra. Not sure if Melifix will affect any of my other fish, especially my 2 Angels. Its a 55 gallon tank. I just dont want him to die on me. i have had him for over a year now. I did remove the ornament he was stuck in also.
