Snail question

[T.o.r.c.h]

I was cleaning my 75g and noticed something odd in the sump. They look like small snails, but their shells are soft. There are 3 of them sitting on my filter pad right where the overflow drains into the sump. I do have 2 apple snails in the main tank. Could these be baby snails? They are about the size of an airsoft bb and gold in color just like my snails.
