I have a 40g tank with 2 clowns, pink spotted watchmen goby, yellow corris wrasse, and a possum wrasse. I am looking to add 1-2 more fish maybe a third if it was a small group of schoolers, but I don't know where to go to be honest with the last few guys and was looking for some suggestions. I will say that I am looking to possible get a cryptic sixline wrasse possibly, because I love wrasses and think they are better looking than regular sixlines and also have the added benefit of being more chill than them.
