My clown seems lonley

[Kleko]

Hello everyone I have a percula clown fish thats acting lonely. He will go up to the glass and bump against his reflection over and over then swim off and do it come where else. Hes young, My tank is 24g nano cube. I do have a coral in there a hairy mushrrom for him to host but its still new.
Should I add another clown?
Thanks,
Mason

your tank is still new and your still watching for a cycle if i recall correctly,i would just wait,some fish do like being in groups but yours will be fine on its own for awhile,remember.....patience will be rewarded with a splendid tank
