Hey guys, got a limpet of some kind here. Keep or sump?

And another critter. Not sure what it is. It's clear and has long strands coming out that look like feathers. Very light feathers. Here's two shots under different lighting.

Plus I just saw this long thin thing zooming around the tank. Then it got mutated by a power head. Have no clue what it was.

looks to me like a limpet or stomella snail in the first picture and the last two are a vermitid snail
