Ok, I?m dipping my feet into housing a PBT in my reef tank. I have never had luck keeping one of these guys, have owned 3 since 2008 and never had success they always stopped eating and developed ick, dying shortly thereafter. My current tank is over 140ga including my sump volume. He is the largest specimen I?ve ever owned approximately over 5? big looks nice and healthy, been at my LFS since April eating well, and actively swimming around. I need advise how to keep it healthy long term.
