New to the site and relatively new to the hobby, here's a question.
I just came back from Jamaica where I went snorkeling, and picked up a few shell, this 'rock tree' looking coral and dead sea urchin shells. I want to put in my tank, I had them soaking in salt water for over a week. Is there anything else I should do? This is a good idea right? I have 2 clowns in a 45 gal
, and I sure don't want to hurt them either
