Barnicles?

[smoney]

I am starting to get barnicles in my tank and dont know if they are good or not? Well, I think they are barnicles let me know what they are?
I have a pic of one that is on my rock and one that is on my snail's shell?

They look like limpets to me.Barnacles generally come in with LR and do not live long.They have a 'trapdoor' so to speak,and you will see little sweepers come out to catch food.I had them when I first started my tank...too bad they did'nt live,they were cool.
