I might have to check out the Vrolik's wrasse. Are either of these a reasonably good consideration for a 90-gallon mixed reef? I would like one, but I have read some potential concerns in a mixed reef, especially if they reach sizes of 7-9 inches (I looked into Melanurus, but did not know of Vrolik's wrasse until now).What you have is a Melanurus wrasse, not a Vrolik's wrasse
