Colinista snails?

Just got these guys out of a frag swap. Are they good or bad?

The pictures are a little blurry, and the video does not work for me, but I believe I am seeing Collonista snails. Harmless algae grazers.

Lemme see if I can get better pics. Are they gonna mess with anything in my tank? Will they clog pumps up?

I have never had them clog up pumps, though maybe others have had different experiences.
