Why are these snails clustering here?

[SharkRacer]

I recently got my first ever CUC from ReefCleaners.org and all my big snails are clustered at the tip corner of the tank, instead of doing their job cleaning my algae off the rock haha.

why are they doing this? Should I pull them off and place them where I want them?

Nerites will cluster at the top of your tank during the day and then become active at night, totally normal.

First, you can’t go wrong with John at #reefcleaners

that’s what nerites typically do.

let them settle and before you know it they will be on the floor. Unless you have a top!

All is good and normal.

Agreed - John was awesome throughout the entire process!
