I have had a red corris wrasse for almost a year. I bought it really small, about 1inch. When I added it to the tank there was quite a lot of aggression towards it, so it stayed in the sand almost constantly for 2 weeks.
While I moved some of the aggressors on and the wrasse started to come out more I noticed it had changed from its normal orange/red colour's to almost black. I thought it was just a result of the stress and would correct itself.
Fast forward almost a year, wrasse has almost tripled in size and has a really beautiful blue stripe on its belly which I assume is it starting to transition. However, it is still almost jet black.
Just interested why that may be, is that normal for this fish?
Pictures show fish under whites as well as blues.
