Are you thinking of altlantics or pacifics? The ones that look like dory from nemo or the ones that look like a yellow tang only blue? I've never kept an atlantic but seen plenty diving in the ocean. They start out a nice yellow color and become a pastel blue as they age. Nice fish. I wonder why more people don't keep them in their tanks?
You haven't think about Orangeshoulder Tang. I had one and it was an algae devorator. they get quite big but I beleive is the most beautiful tang, with a coloration that I haven't seen in any other fish
Just in case you were still wondering about the Atlantic Blue Tang, I figured I'd post some pictures of mine.
I have 2 of them that I caught when they were literally less than an inch long. I originally had 3 but the 2 bigger ones ganged up and killed the smaller one . But the 2 I have left get along great now for the most part.
When I got them they were a bright yellow color. Now they have morphed into a dark florescent blue (the flash kind of kills their color but you get the idea).
The 2 I have are about 5" and growing. They are in a 210. I know they can get quite big in the wild, so one day I may need a bigger tank. Hope you liked the pictures.
Yes, like most tangs they do show some signs of aggression once in a while. Like I said, I originally had 3 of them and the 2 biggest ones killed the smaller one. That was months ago though and the 2 I have left seem to get along fine with everyone else. It's almost like they out grew their bad behavior and now get along with everyone.
The reason i was wondering is that my LFS has one and they said i could have it cause they think it is too mean! I dont want to add it though if it is going to kill my other fish. This one is bigger than my hand.
