Can anybody please give me advice on my Regal Tang that seems to have suffered some fin damage.
I have had my marine tank running for 18 months, with very little problems. About a month ago I added a Regal Tang to my Tank roughly the size of a pound coin. There was an initial problem with the leader of a shoal of Domino Damsels(yes the worse mistake I have made) who constantly chased the poor Tang, but it has hung in there and seems quite happy now and content with a Clown and Valentini Puffer. He also regularly butts a big Niger Trigger who duly ignores it.
Sadly a couple of days ago, I noticed the Regal had suffered some tail fin damage, firstly one tiny white spot appeared on its tail, now two. The fish seems as happy as ever and doesn't seem to be suffering any ill affect.
Any advice would be greatly appreciated
