wow prity small tank but doable the damsel probable has setup on one rock and the clowns on the other. as long as it stays that way teritorys are defined. There is a parisite that seems to be photo sensitive comming in on fish right now. when you first turn on the lights is there anything out of the ordinary with the clowns? is ther excess slime coat on the clowns. as I said look for any behavior that is not normal with fish like shaking its head and exhaling water fash usly a sign of infection in the gills.
so be on the look out and watch for anything and do the water sample.
