Thanks for the comments! The tank has been running here for 2 1/2 years now, and I'm finally at a point where I'm fairly happy with it!
When I move it into the new tank and glue all the corals down again then I should be quite happy!
Leah, that is actually a Melanarus Wrasse! He is
very blue. He was a she until about 3 weeks ago he started changing into male, and turned this lovely blue color. I will try to get a close up pic of him. His fins are almost as blue as a Mandarin's fins.
