+1 .. they live right in the surf zone in the wild. Very strong swimmers!

To be honest if it were me and this my tank, I don't think, that I'd consider it for a 4' tank. They'll do so much better in 6' or more. Maybe if you found a small one with the intent to rehome down the road (or upgrade) but IME small versions of large fish rarely stay small for long. Probably not the advice you were wanting to hear, sorry!!
