Astrea Snails Clean Each Other?

[Big Mistake]

So I have had various Astrea snails in my tank.

One has outlived all the rest (a question in itself.)

So for while it was a lonesome soul, its shell had gotten sort of fuzzy.

Added three new Astrea friends, and sure enough, old lonesome's shell is now as clean as the 3 new Astrea friends.

Can't tell them apart.

So they must know about each other; did not randomly clean lonesome's shell by just running into each other.

Maybe grooming each other is part of the Astrea snail mating ritual.

I guess covering the tank at night might have other benefits.

They do as well as turbo, margarita and trochus

Golly gee, snails are people too.

All sorts of monkeys, apes, and hominids groom each other.

In a bath or a shower. I've washed a back or two.

From Science Daily:

Research shows we're surprisingly similar to Earth's first animals​

Today's humans share genes with ancient oceanic creatures missing heads​

Missing heads might be the key to happiness.
