Your tank is coming along nicely, nice to not have algae issues.
A few things to note... Bumblebee Snails are known to not always be 100% reef-safe. They are known to eat Zoanthids and other polyps when they are hungry. Also, your hermits will eat the Cerith Snails when they get hungry too. Hermits are opportunistic predators, Scarlet Hermits are the lesser of the evils, but they too have been known to cause grief with Snails - especially Cerith and Nassarius.
