What is it

I set my tank up Friday and I noticed this white thing after the water cleared. It's about 1" long and has moved about 1/2" since Friday. I'm wondering if its anything I should be concerned with? Also would it even make it thru cycling?

well if you had found it out in your yard i would say it was a slug. it is probably not harmful BUT you never know. i think if it was me i would take it out if i can't identify it.
