Hey, I was at my LFS recently looking into fish options for my 20-gallon Innovative Marine tank, and someone there recommended a yellow watchman goby. I mentioned that I only have a shallow sand bed, around 1 to 1.5 inches, and they said it should be fine as long as I don’t pair it with a pistol shrimp. I was still a bit unsure since I know yellow watchman gobies like to burrow, even without a shrimp partner. I haven’t done much research on them yet, so I was wondering if they can still do well in a tank with a shallow sand bed. Thanks!
