NO DAMSEL'S!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! 99.9% people regret getting them because they are mean, Chromis are the only nice Damsel. Your clown does not need to host with anything. Your tank needs to be well established before you have nems, like a year-ish. Also dont forget most clowns are aggressive even though they are listed otherwise, its not usual to have a good natured clown. Your tank need to be up and running for 40-60 days to cycle anyway so you have plenty of time to decide on fish and coral. Also cycle it without the lights on as it goes faster and wont grow so much algae.
