hello everyone! So I am doing some research on dwarf seahorses and I'm pretty sure I'm going to get some!☺️ Anyway I am having trouble figuring out what coral is safe for dwarf seahorses and where to buy it. I have been on other websites but people take forever answering questions. Anyway thanks for the help in advance!!☺️ If you have other advice that would be helpful feel free to add it. Thanks!!
