I can't find the original thread of when my mate Ian and I caught this Emperor angel, but it's now starting to change into its sub-adult colouration. I thought I'd update this thread with changes as they happen. It's quite fascinating to watch really. Does anyone know why they change so dramatically, whereas some fish stay the same throughout their lives?

not sure, some angels change fairly quickly into their adult colouration. For example Navarchus, from smaller than 10cm. Others change a lot later. But the radical change is still amazing.
 
Coral fish are highly territorial. They display most aggression toward others that look like themselves (similar fish will be competing for similar or the same resources, such as food, mates and territories). Juvenile specimens of many species have a very different color pattern to adults, to discourage the older, more powerful fish, from attacking them.

That would make sense! :thumbup:
 
Emperor Color change

That's a great sequence of pictures. Would be very nice if you could post them in this thread as well. Then we can compare time span etc.

Beautiful! I'm green with jealousy right now..... :thumbup:
 
Ja Seun.... I'd also sh!t myself if you were the first thing I saw in the morning. But seriously, it grunts when it sees movement in front of the tank, at feeding time, when other fish are crowding it and at lights-out. So I think it's probably a dominance tool.... Kinda like "grunt, grunt... beat that my scaly friend".
