Definitely planning to add a pistol shrimp goby pair too. Along with a red scooter blenny a canary blenny and a pair of clowns. But don’t wanna go too crazy with the small space I have. My pearly jawfish is currently my favorite animal in the tank. Awesome personality and a cool color. I’ve had two pairs of clowns but for some reason both pairs died and I can’t figure out why so I’m taking a break from them for now. Very strange when everything else is doing really wellThanks but the sand depth varying is all due to my pistol shrimp... moves around sand all the time and gets on my nervessssss!! But my pistol shrimp-yasha goby pair has been my favorite relationship so far.
