My Lionfish seems to have gone blind, I don't know why. They had ick for a while after we changed them into a bigger tank but we got rid of the ick. I noticed the Lionfish not eating silversides when I threw them in, so I went and bought him crayfish, that's when I noticed he couldn't see them. He swims in circles or just stays laying down on a rock. My husband suggested doing a mercy kill because he is going to die if he doesn't eat, but I feel so bad, is there any way to save him or should I just sacrifice him and stop his suffering?
