Ian wrote Is it normal to have worms (look like common earth worms) and some
white
thingies that look a bit like snails without the shells (or grubs or
something, about an inch or so long) in one's pond?

Yes, the number of critters that live in water is huge.

I've even seen a goldfish try to eat one of the white thingies, hangs out
the mouth an inch or so.

This one though.... almost sounds like anchor worm.
