Quarantine tank size

[Zfusco]

I've got a 55g Display, and Im looking at adding a quarantine.

Just based on the size of the tank, I wont have anything huge like a tang or anything, so I was wondering if a 15g is too small to use a quarantine?

So far I've got 2 clowns, a wrasse, and a midas blenny. I dont plan on adding anything larger than a CBB later on down the road.

I have a similar sized display tank and use a 20g tank as my qt. I think a 15g should be adequate.
