My mystery wrasse has been hiding under a rock piece for the last couple months, don't really come out swimming much. But at feeding time, it did look out and grab a big piece of frozen then went back, much like my marine betta. Couple days ago I was doing maintenance on the tank and moved its rock, but this time it didn't go back to it afterward, and just hide under a small piece of rubble nearby instead, and didn't move at all even at feeding. I noticed its right eye seems to popped out a bit, like drop eye. Yesterday I tried to catch it out to see if I can do something about it, and managed to catch it bare hand ... Now it's in an acclimation box in the display tank.
What does it look like the problem is? What should I do next?
