can't have the tang, tank to small and you can't have the Linkia Star, they don't do well in tanks, esp not smaller tanks.
I just ordered 79 bucks worth of inverts from here that I liked and that would get along.
I have a CSB, arrow crab (though I'm not sure about him), a brittle star, cc star, 3 urchins, 20 assort. hermits, emerald crab, some other crab.
You can get 10 pepermints, 30 or so hermits, serpent and/or brittle star, urchins, snails. whatever you want really. Or CBS shrimp, they are cool but don't mix with other shirmp.
But the linkia's don't live long in tanks, if you have a large tank with LOTS of lr, then some will do okay, but most starve to death within a few months.
you can get a package from this site, but I've found most of them aren't that good. They come with creatures you can't have together, I learned the hard way last time after the CBS ate all ten pepermint. 55-100 Gallon Reef Package still has pepermint and CBS but the two before that seem okay, a bit boring though.
