Seaweed From The Ocean

[brianc60]

I Thought That I Read Somewhere That You Might Need To Add Seaweed To A Rock And Drop For Crabs And Such. Can You Use It From The Ocean? Also Could You Add The Small Snails That You See On The Rocks?

Putting anything directly from the ocean in your tank is a risk. Yes, it's true that most of the livestock we use comes from the ocean, but the shores of the US (I assume you are in the US) are not very clean... pollutants and such, not to mention running afoul of the authorities... most shores have collection laws..
So yes, you can add things from the ocean, but weigh heavily what you want to do.

also, us water is generaly much colder, so the snails on the beach are suited for cold water and will die in a month or two in your tank
