Getting started... Again

[droidus]

I have a 32G biocube. Currently, there's nothing in it, and it's been cycled. It has been running for a few weeks now. I would like to eventually place 2 clownfish, a goby and pistol shrimp, as well as a cleanup crew.
In regards to the cleaning crew, I know this is usually where to start, but if I currently am not putting food in there, then there would be no food source for them... so would it make sense to get the cleanup crew and the fish at the same time?
After watching a BRS video on cleanup crews, they mentioned about 1 snail/10 gallons of water. Before when I had my tank established, I have 12 zebra hermits, 3 nassarius snails, and 6 spiral top trochuses. Looking at my notes, and least 8/12 hermits died, and I'm sure there were more of each that died. I think it is due to there not being enough food source for all of them.
Also, does it make sense to have a cleanup crew if there is no visible algae? I know some will sift through the sand...
Also appreciate advice/mods to the cleanup crew from before... I don't think it's appropriate to have that many this time. I would also like to add a peppermint shrimp this time!

 

[Spare time]

I usually say wait to get snails until you see algae on the glass and add hermits two at a time (with some spare dried out shells for them to grow into. As for what to get, I would say maybe 4 hermits, some snails like turbos, a couple of nasarrius a conch or two, and eventually an urchin if you get enough algae or don't want as many snails (urchins are my favorite). You can add however many shrimps.


Usually people get their fish and then wait a week or two before starting their cleanup crew.

 

[New&no clue]

I did it the opposite. I add a small CUC first to stay ahead of the algae, I feed a couple pellets every week. I also keep more than 1 per 10 gallons. I have roughly 1 CUC for each gallon. So in my 75 I have 75+ snails and hermits of all different types and sizes, in my 30 I have 30+. I add them slowly over the first 3 months or so. My 75 is 8 months old and I get a little bit of algae here and there which is quickly taken care of. My 30 is newer so they are working hard to keep it clean. They eat left over fish feed (I feed kinda heavy) they pick at the nori clip and when they are bored they clean the rocks.
