Dear hobbyists, I've seen the rarest tang of them all,its called A Powder Red tang.( Not A Powder blue ) They've been recently discovered ,and the trade hasn't even put a price on this species of fish, but when they do ,you can believe they will be costly . This Powder Red tang looks almost like the powder blue tang,but its body is and tail are red. Just when you think we've seen it all, out comes a new species of fish.
