Hi everyone,
I have recently gotten a fish book for christmas and I have found that it is a bit dodgy. It says that the blue tang grows to only 15cm in captivity where as it grows to 31cm in the ocean. And the yellow tank grows to 7.5cm in captivity and 20cm in the ocean. Is the true????? Please Help, how big are your yellow/blue tangs????
 
I use fishbase. It's an actual scientific compilation, and is updated constantly.
Zebrasoma flavescens: 20 cm
Acanthurus hepatus: 31 cm
I would doubt any site that gives a value for max size in aquaria. As far as I know, the data haven't been gathered.
 
Thanks for your help everyone, I have decided not to have any of those two anymore, but I am now considering a powder blue tang instead.
