Stomatella snail. Common hitchhikers and beneficial algae grazers that multiply over time.

I can't decide if it's a stomatella or a sea cucumber? How big is that monster?

You can tell it’s a Stomatella snail by the siphon and pair of tentacles sticking out the front. Sometimes the foot of a Stomatella can grow rather long, making it resemble a slug or sea cucumber.

I'm reduced to a quivering mass of self medicated sunday afternoon depression gearing up for Monday and I thank you for clearly marking up the picture, and posting 'Stomatella" as my vision and metal state are not acceptable for making fine determinations from visual stimulus atm.

Are those tentacles or testicles on the photo?

It’s about a 1/2 inch long.

Yup, I do believe it is a stomatella, looks like a slug but it has a shell. They eat what they find in the tank and are part of a good cleanup crew.
