I would skip the Mandarin (needs lots of pods
or will starve), the triggerfish (needs 70G and will eat your inverts), lawnmower blenny (will starve without a natural food source..mostly algae and hair algae).
If you plan on doing corals, the flame angel may eat them.
I would go with an emerald crab, skip the sally lightfoot.
I would also get fewer hermits (just my preference) and go with a bristlestar (not the green ones) nassarius, cerith and margarita snails.
Cleaner shrimp are great you can add a fire shrimp too.
Personally, I like the pistol shrimp goby combo.
