yep, dwarf ceriths, got it from reefcleaners, some do bury themselves but because i have so many, a lot of them end up on the sand bed, climbing rocks, on the glass. I ordered 28 and I think there were 100 of them in the bag... Nerites are alway on the waterline, clinging together....
I am SOO GLAD this thread got started!!
I too bought a custom CUC crew from reefcleaners. Right away, the cerites climbed the FRONT glass ONLY - NEVER the sides or the back (which, ironically, need the MOST cleaning). JUST THE FRONT! So John tells me in a few days they will "freak out" less and start to spend more time elsewhere. Well, it's been WEEKS and they STILL climb the front ONLY.
During the day, they litter the sand looking dead.
At night, they climb the glass and all clump together in one spot (John DID say they were "social").
IMHO they are worthless as algae eaters.
My nerites climb OUT of the tank, and if they don't they spend 90% of the time at the water line, cleaning what little algae is there.
When I put these snails on the LR (which NEEDS the cleaning), they spend a little time there but eventually climb off and just go back to the front glass.
I put all my nerites in the sump.
Ironically, the few hermit crabs that I said I did NOT want (but somehow John shipped me anyway) are doing the best job of picking away at the film algae on my LR but they obviously don't clean the back.
Should I get some trochus or turbos?
