2 months...hmmmm
well he got over the opening day jitters alright.
IF the water conditions were ok (All aspects) I will have to think a little bit. I have had some weird things happen to my tangs over the past few years. They tend to stress very easily and like to lie on their sides some but not near the top. Is there a possibility that something foreign was dropped into the tank????
If I can think of anything substantial I will post again...
