FIRST THING, buy nothing at all, let the tank go for one month, the ick will die off itself, if you have lr and sand, you should be ok for bacteria, but you do not want to add anything that can get ick itself for one month(after your last death)
how old wasyour tank,
adn did you quarentine your fish b4 introducing
and for your answer, i like fire fish, clowns and cardinals for that size of tank, may be even a blenny , but yes, NO tangs should be added
HTH
