Need advice on qt size?

[derrell]

I need to quaritine some tangs and reef safe dwarf angels but worried that the 20gal qt I have will be to small to qt them even if I do them one at a time. Any thoughts? If the 20 is to small what is the smallest I can get away with to at a larger fish?

You might go for a 40b. I used one to QT two tangs (I usually use a 20 gal) and it worked really nicely. PetCo might still have their dollar a gallon sale. It was going on last weekend.

How many tangs and angels are you QT'ing?

FWIW and YMMV, I QT'ed 6 adult tangs (5 Yellow and 1 Purple) together in a 30g for a couple months with no problems.
