so, after further research I think it's safe to say it's a baby nerite snail. As, I haven't bought a nerite snail in over a year or more and they seem to keep a good presence in the tank. Only bought 5 that came with CUC pack. I have at least 15-20 If not more at this point. (Gotta love reefing, always finding or figuring s&*& out!) lol!
