Explosion of sunburst anthias all a sudden. Do note those who are interested, they require some feeding training initially to accept frozen food, followed by pellets. May be difficult initially due to its timid nature and food competition with other fishes. Mutiple feedings a day will be best, prepare for any nitrate spike if your tank can't handle increased amount of frozen food too well.
It will only come out if its comfortable with its surroundings and tank mates, avoid if you have any aggressive fish in the tank, such as damsels. They do best on their own, due to aggressive nature against its own kind. But that said, u can be lucky with a pair or a small grp still.
Still my favourite fish till date. Small and such a beauty
