No.
Anything but a handful of types of fish would be happy in such a small tank. Tangs like to swim and should be given a larger tank.
O.O
IMO, no fish should live in a 5 gallon.
Unless its temporary. "Fish and light not for sale"
I'd imagine its to make the tank look good.
Awesome. I have a Fluval Spec V sitting right next to me atm. I'm going to run to Petco right now and pick up one of those white color morphed Yellow Tangs, the ones with that Skelator look going on. Oh maybe I should pick up 2 so the one isn't lonely.
Actually, for that size tank I would reccomend a sohal.
Oh, that's a good idea! Instead of 2 yellow tangs maybe a Sohal and a Queen Angel to keep him company.
