ID on these snails

[FishDooD65]

I found these snails near the beach in Key Biscayne here in Miami. They were hanging out on the rocks near the shore. They look like a type of Nerite snail, but I’m not sure. Any ideas?

Shells look like that of triton snails (undesired) but antennae looks like margarita snails (desired). Not sure if I would want to take the chance

It doesn’t have the bushy antennae like a triton snail. It has 2 antennae.

I think they might be Nerita tessellata

I put them in my tanks, they graze on algae. Mostly nocturnal and will climb out of the tank. Eventually some settle in. Here’s a couple hiding and their egg sacks.
