Tangs are big swimmers and fast growers and I would not add one to a 36" tank. There are many fish that eat algae. Also some people have good luck with hermit crabs eating HA but none of mine seem to. The question always is will the individual fish eat the algae in your tank????
I currently have an Atlantic Pygmy Angel in
QT and it is a dedicated herbivore. I am on the downside (hopefully) of a HA outbreak and have pulled some from my
DT and given to him but he mostly ignores it. Maybe it would be different if the HA was still attached and he could graze it from the rocks.
I think that good husbandry and growing macro in a
refugium are the best ways to control nuisance algae. And not going on vacation and having someone else take care of your tank.
