I’m going to be breaking down my 6g nano, and need to find a new home for my goby/shrimp pair. I’ve had the shrimp for two years, originally paired with two yasha gobies. After both those made their way out of the top of the tank, we got the Randall’s, which was more than a year ago. Fun to watch, the shrimp has an anthill-type cavern excavated throughout the tank. $50 for the pair
