I have a 70 gallon fish tank with 2 plecos, 3 cichlids (Green Terror, Jack Dempsey and Blood Parrot) as well as a Red Tail Shark. The Red Tail is much smaller than any of the others, but has grown up with all of them as she was one of my first additions to the tank. I have never seen any of the others exhibit aggression towards her, nor vice versa. Today, I noticed that she was missing an eye and is very torn up. The eye is just missing completely from the socket on one side. I immediately removed her from the tank and put her into a bucket of warm, salted and conditioned water and have been monitoring her for about 2 and a half hours now. She is floating upside down and has been for about an hour. I know this is sort of a lost cause, but I'm wondering if maybe it is just disorientation due to her new lack of an eyeball? She was swimming sideways for a while, and has deteriorated and cannot seem to swim right side up now. She is still moving and seems to be trying to swim, but every few seconds she stops and remains still, before continuing to move around a little bit. Honestly, I'm not sure if I should see if she makes it the night or if I should put her out of her misery.
Please help.
