Here's my experience with Anthias. I have a 32 gal tank. Had to have an Anthias because they are so pretty! Mine is a breeze to take care of and SO funny! It thinks it is best friends with my Skunk Shrimp. The shrimp...not so much. For hours on end the Anthias hangs out upside down with the shrimp. It loves to be cleaned but the shrimp gets tired of it so the fish has decided it will just hang out.
