IMO your already near max capacity with your current line up.
Even if you go with just the two clowns and three chromis.

The clowns once mature will start to breed, this will cause them to become aggressive and not tolerate others near their "host".

Chromis are prone to squabbling when not giving enough space and will end up picking on the weakest of the group until it dies.
