Stars & stripe puff w/ dogface puff?

[hasq]

I have a 220 gal. with most of the bells and whistles for a FO tank (approx 6mo old). Currently I only have the following fish: 7" stars & stripe, 7" California ray, and two blue damsels. The question is would I be safe to add a dogface (5" or greater) to the mix?... What about a Niger with the puffs and the ray?

Adding the dogface will be fine. Try to get one thats within an inch of the other puffer. As for the Niger, buy him last. If you put a Niger in too soon he will think that he owns the tank. He can be very aggrissive. But adding him last will clam him down. It will even help to get him a little smaller then the other fish. Hope that helps.
