hey guys I just got back from a month vacation where my roomate fed my fish every other day. No water changes, he didnt even add water so it dropped 4 or 5". Tank is 110 gallons and is a tropical community, it seems like I have no losses but my smallest cory. The only peppered cory, has lost one of his eyes! I thought it was dead but it was breathing then I fed the tank heavily and it was swimming normally and ate! Its a clean socket but idk what to do. Has anyone else ever had anything like this happen? Idk how long the eye has been gone and you can see like into his head its very odd.
