How many inverts should i have?

[jrogers3105]

So my tank is 75 gallons and 6 months old, my sand bed ranges from 2inches in the lowest spots and up to 4 inches in others. Plenty of live rock high and low.Here is my currents estimated invert count
1 mexican turbo snail (started with 3)
2 bumbles snails (started with 3)
~4 astrea snails (was 5)
~12 dwarf blue leg hermit crabs (was 15)
~4 jumbo nassarius snails
~6 common nassarius snails
~6 trochus snails
~ 3 red/blue legs hermit crabs
1 halloween hermit crab
1 fighting conch
1tiger pistol shrimp
(i've seen the legs of 2 different small brittle stars peeking out the rocks if that means anything)

Is this a good count of should i be upping my snails/ hermits? I also recently added a lunar wrasse who hasn't not shown interest in the snails or small hermits so should i not be worried about overpopulation and just stock up?

Do you have algae in the tank? Do you overfeed a lot? This is what determines if you need more clean up crew. To me it looks like your clean up crew has died down to what your tank can support so I would not get more myself. Personally I re-stock on snails once every one or two years.

If your algae is being handled properly by the CUC you have? No need to change anything, however once algae ramps up, that is when you should add more CUC.
