一礁不容二魚：條紋蓋刺魚／皇后神仙幼魚的白藍圈圈到底可以幹嘛？One nation can’t have two queens, since the potential one is still young: Juvenile-adult colour patterns & coexistence in the territorial Emperor Angelfish
條紋蓋刺魚，又稱皇后神仙、主蓋刺魚、條紋棘蝶魚、大花面是水族玩家及潛水攝影愛好者的心頭好！其幼魚和成魚的體色差異極大，小時候是絢麗的白藍圈圈，長大後卻變成黃藍條紋，如此大的變化究竟是為何？
研究發現條紋蓋刺魚的成魚好鬥且有領域性，但成魚對身旁的幼魚卻較能容忍而不去驅趕，意思是一礁不容二魚，但看你還小就不跟你計較啦！

The Emperor Angelfish (Pomacanthus imperator) is famous for its exquisite color patterns among aquarists and underwater photographers. There is a huge coloration difference between juvenile and adult fish, from blue-white-circled to yellow-blue-striped.
Why so different and what for? Research shows that territorial aggression adults were less likely to attack juveniles of their species than adults. We all know one nation can’t have two queens, since the potential one is still young, doesn't matter!
