Snail Escapees?

[dacia]

I named 3 of my 4 snails. They are Stupid, Dumb, and Dumber. They keep crawling up the side of the tank towards that small space where water flows back into the tank from the filter...they will actually sit on top of that in the waterfall.
They aren't going to crawl out, are they? I had one making his way to the hood from the filter, and I nudged him back the other way. Is this normal, or is it that the names I gave them just fit?
I think my water is fine:
pH 8.2
specific gravity 1.023
ammonia 0
nitrite 0
nitrate 20 and falling
temperature 79

what kind of snails? My turbos get close to the top, but have never tried to escape

They are turbo snails. I now have one that will perch on top of the powerhead at night.

Maybe they are just trying to get in on a little romantic dip by the ole waterfall thing or something...

I keep my nowl (normal oper. water level) approximately 1" below the top of my tank, and on a weekly basis I'll find a snail who's climbed above the water line on the glass.

My turbos do the same thing, once they feel like they are getting dry, they venture back down into the water. I know they are dumb but i think they still have the desire to live.

we had some black and white snails that liked to be out of the water. they were either on the top of the glass or on the fliter where the water flows down.
