I go colleting all the time and as Ryan said, not all coral are connected to LR.
Just study the FWC website and know what you can and cannot take.
It's a lot of fun, I was out in 2 - 3 feet of water last weekend and found a beautiful blue mushroom, gorgonians, zoanthids, seamat, lettuce nudibrach, decorator crabs, anemone shrimp, rock anemones, astrea snails, nerites, ceriths, sea stars etc etc. Pity the water is getting too cold for me now....
