Maybe I'm a little contrarian but I wouldn't add much of a cleanup crew at all until you start seeing some film on your glass and especially on the rocks. The diatoms will run their course and show up sporadically for the better part of the first year from my experience. You may want to just let it do its' thing for now. Once the diatoms start dying off your cleanup crew will too unless there's more for them to eat. I lost a lot of nice cerith snails and hermit crabs from adding them too early. Never mind that my leopard wrasse would flip the hermits over and pluck them from their shell, only to introduce them to the Vortech MP40's propeller to mince them for a quick meal. :rolleye1:
