Multiple puffers in one tank?

[cornraker]

I have a porcupine puffer in my tank now with a yellow tang. the tang is about 3 inches and the puffer is about 4. would adding another puffer be ok? not another porcupine but maybe a dogface or a little valentini

What size tank? What all is in the tank -- fish wise.

sorry i thought i mentioned tank size. its a 125 gallon 6' long. 35 gallon sump. just the tang and porky is in it

No. I wouldn't try it in a tank that small. That's normally the minimum size recommended for a porc puffer. Tang is fine, but not another puffer.
