everything should do fine. ive got pretty much the exact same in my 30 gallon, except switch the ceriths for turbos. and ive got a mix of scarlets and zebra hermits.
if i could do it over again, i would have skipped the turbos and went with ceriths, and went with all scarlet hermits, just like i told you to do. only thing is that the mexican trubos are a little bigger than your avergae snail. im not sure what mine are eating, but theyve been alive for over a year, and they did mow down that hari algae when my tank first went up.
