I bought it as a juvenile (~2-3 inches) over a year ago, it has since grown to near adult size (4-5 inches) and is now the dominant fairy wrasse in the tank, though i only have a longfin as it's competitor.
When you say submale, do you mean sexually dimorphic, in the process of becoming a male?
Is there a difference between male and female solar wrasses- i.e. are the males more brightly colored?
