I have 1 clown with hopes of adding one more fish someday, clean up crew(snails+hermits), and a fire scallop. All have been doing great. I would really like to add a shrimp or preferable 2. What should I go with? I not only want them to have the room they need but some say they do better in groups so I'm not sure what to do. I was thinking either 1or 2 skunk cleaners or blood fire? Or one of each but I'm afraid they may get to big. Anyway I'd appreciate the advice. Thanks in advance. Also a + would be if it's the most beneficial to the tank itself
