Sounds like things are going well 
You're going to want a lot more snails, especially since you've just added quite a bit of bioload (two fish) to the tank. While I admit it's probably overkill, here's my 30g cleanup crew ATM:
1 - skunk cleaner shrimp
1 - emerald crab (1")
1 - scarlet hermit crab
12 - mini blueleg hermit crabs
1 - crab (LR hitchhiker, unknown species, possibly Mithrax) (1/2")
1 - Trochus snail
10 - Astraea snails
2 - Mexican turbo snails
2 - Stomatella snails (LR hitchhikers)
5 - Nassarius distortus snails
9 - Nassarius vibex snails
They were added gradually over six months. I'm surprised to add it up and find that there are about 30 snails and 13 hermits, as well as a few larger cleaners, I didn't think there were that many. With a medium bioload (1 fairy wrasse, 1 yellow clown goby and 1 prawn goby, the cleaners and corals) I'm sure there's plenty of algae for them to eat. They keep the rocks absolutely spotless and the sand nearly so, but I still need the Mag-float to tackle the 'dust' algae that builds up on the glass - the snails rarely bother with that, so I know they're not starving. I do throw in some meaty foods once a week or so to make sure all the Nass. snails and hermits are getting enough to eat.
Keep us posted on how everyone's doing
