so for the last 2-3 days my vlamingii tangs eye has gotten worse and worse and today he was hiding and not eating and i was able to catch him easily so i put him in the QT tank in my garage does this look like pop eye? or an injury? i have ERYTHROMYCIN on hand is there anything else i can do to help ive had him almost 4 years and im scared im gonna lose him i thought if it was an injury since he was still eating it would get better
