I am from PR and moved here about 3 years ago. I am pretty familiar with the local hobby scene, collection practices and the snorkeling/scuba spots. So let me know if you have questions.
Please note that it is not legal to collect any type of corals or rocks from the reefs. They are protected under Puerto Rican Law 147 (Coral Reef Conservation Act of 1999) and the US Coral Reef Protection Executive Order 13089 of June 11, 1998.
BTW, this time of the year, the Caribbean sea side of the island (specially the south / south west) tends to have better snorkeling conditions than the Atlantic side.
Hope you enjoy the island.
