Hello! Just walked by my Reef tank and noticed my Squirrel fish has an eye that is HUGE. I know it has something to do with the oxygen in the water...but...what the **** do i do for my lil ' guy???? (I just did a %20 water change and i don't know if he was like this before i did it) Help!!!!
I don't know if it is the same for SW fish but there is a disease in FW fish that will cause eyes to bulge out. I think the FW disease is called Pop-eye. If you can't find an answer here or elsewhere online I recommend calling @Preuss (517) 339-1762. They are very knowledgeable and should have a solution for you. Good luck and I hope he pulls through.
