1 more tang...too many fish?

[Troy F]

I don't think so. I have a really small 1.5" yellow tang in my 155gal reef and I would not put this fish in anything less. I've had a yellow tang in my 72gal and I thought that too small as well. My personal view is that Scott Michael's book is a good guideline for minimum tank sizes but if anything I'd go bigger. A Naso doesn't belong in a 135 in my opinion. There are lots of fish that he lists with a certain size tank that I'd disagree and say they need a bigger tank. Centropyge spp. is a good example in my opinion.
