I use small painters buckets I get from lowes for like $2 each and set up a small army of them along side the tank. LOL
The most I've ever done has been 7 fish and inverts I believe. It was a bit hectic and messy but it was fine in the end.

I have a mix of many different saltwater fish amongst my tanks, but I love my Tangs most of all.
