Is my custodian package enough.

[BCReefer]

I have a 33G tank and my custodian package is only 6 – 7 turbo snails and 3 – 4 hermit crabs. Is this enough? I hear that you need 1 crab for every gallon and 1 ½ snails for every gallon. I prefer not to get anymore hermit crabs as I have been hearing that they can get nasty.

I have a little algae on the glass that I clean with the scraper but so far no major algae out break.

Thanks
