My yellow tang was a bit too curious and get suctioned by the powerhead. I found him attached by this eye....not able to get out, and quickly cut the power. When he was released the eye was bulged out, while the other side was pushed inwards. Has anyone came into this situation before? Any suggestions for me? Leave it alone? or push it in? : ( So sad, i've had him for 2 1/2 years.
