Our tank is 230g. It is an open top tank, so if anthias are jumpers I'm not sure I sould get some, I'd hate to spend a bunch of money on them just to have them jump out
. Also with them being hard to feed I'm worried our "piggy" tangs would eat up all the food before they could get some. However I do feed a lot of mysis when I feed my tank, which is usually once a day, and so far everyone (including our very slow eater, our mandrain goby) gets some. I also feed pellets and nori.
