Well got home tonight and looking in the tank and seen the Blonde Naso Tang laying on his side in the rocks! so got out the net to get him and he took off swimming but his color is black now. ( i just got him 3 days ago and he was doing good till today) after he took off swimming he stopped in the back of the rocks and has not moved. i feed the fish but he did not eat. i turned off the lights.... what can i do?
