I have heard that the Powder Blue Tang is the fish to get to tell If our water quality is good. If it turns pale then your water quality is poor! Don't quote me on this though. Like the above said youmight want to check the disease forum!
I had a boxfish. It lived in my tank for about a year and then one day just died! I was away that day and came home to find every fish dead! All the water peramiters were fine. I was uneducated about this fish and if I knew I don't think that I would have got the fish!
I wish I had a camera to take a pic. My perc doesn't use my colt like an anenome, but when the lights go out he goes to sleep the whole evening in the colt. It is the cutest thing!
My live rock sits on a very thin layer of CC. I have not had any problems but I have also built a good layer of cc around it too!
6 years and no collapses yet!!!
I have heard that anthias should really be bought in pairs as they do a lot better with a partner. I had this problem when I purchased one and he looked depressed most of the time. When I put the pair in they both did well.
