Suitable tangs for 4ft tank

[Underwater]

Well, in light of the "pro multi-tang" atmosphere, here's my list:

Naso Tang
Regal Tang
Sailfin Tang
2 Mimic Tangs
Clown Tang
Powder Brown
Antlantic Blue
Kole Tang

(And that's just the tangs) I keep these is a 150 gal-that's 4 ft long-but really deep. I have about 150 lbs. of live rock in the tank and another 80 in the sump. I have never had a problem with fighting, being territorial or eating. They are all kept fat, happy and sociable. I think that as long as you pay attention to the fish, they will let you know what is working and what isn't. People may have their "rules" about what can or can't be done, but every case, tank, situation is different-and not all rules apply.

I say go with your gut and let your fish tell you how to proceed.
