I recently moved everything from my 10 gallon aquarium to a 20 long in hopes to be able to house a pair of ocelaris clowns. I lost my firefish on august 15th to ick, so the tank is going through a fallow period. current corals are 2 blastomussa, and a hammer, aswell as GSP. would it be ok to add a cleaner shrimp or will it bother blastos? also anyone know what date it will be safe to add the clowns?
