Special glowy female! u3u

Have decided a little more background for these guys, different colours are representative of different 'schools'. While they tend to feed alone or in pairs, they tend to prefer their own type for mating, which keeps quite a few different groups, each tending to specialize on their own reef or coastal niche, that can still interbreed between groups (mostly). Different schools have different levels of individual differentiation, and it's up to the adopter how unique they want their particular fishy to be in comparison to it's base school~
