i have a 30 gallon tank, with lps corals, 2 perculas, 1 six line wrasse. I'm looking for one more fish to add to my tank but i'm not sure what. I really like anthias but it seems like they all need a large size tanks. what fish would be a good addition to my tank? my six line wrasse is very friendly. I've had him with a firefish before and they got a long really well
