So, I was interested in the yellow watchman goby and yasha before I had even started my tank, and I'm looking into getting whatever one my fish store has. So I have a 24g cube, 2 clownfish (still being annoying and fighting, I have seen some submission, so it should be over soon?), an orchid dottyback, and a bicolor blenny. the clowns don't really have a set territory, my dottyback hangs near a cave at the top and sits in his burrrow in the sand, and the blenny hangs near the top and wedges himself in a hole (or just anywhere where algae is). None of them even interact except the clowns. There is a large cave in the middle that my shrimp stays in and if someone comes through he doesn't care, and it even cleans my blenny. So would that be ok to keep a goby long term, and since I hear he might run out of food in the sand would getting a baster or something and putting frozen or pellets on the sand bed to makes sure he is eating? Thanks for the response.
