Welocome. Another guilty part y of starting out with a dark and light blue gravel mix with the terrestrial plants sold as aquatic ones at petsmart. I have never been to the dominican republic but i did make it to haiti as a teenager. I went as part of a mission trip that worked in orphanages. I saw a lot of things but the coast was the most beautiful sight i have ever seen (besides the face of my son). Plant on!
