Hey all! I have a 29gal mixed reed tank with a 20gal sump. I currently have a pair of premium phantom clowns and plan to add a midas blenny, royal gramma, and fire fish. My LFS offers blue-legged pistol shrimp, tiger pistol shrimp, and Randall’s pistol shrimp. Which one of those is the best? What are some small and peaceful gobies that would fit well in my tank with my stocking list? Thank you!
