My problem with gobies is they seem to just waste away after several weeks!. It is usually very difficult to get sand sifting gobies to eat prepared or frozen foods. These fish need a lot of food to sustain their body weight and it amazes me that they even survive in the wild.It just goes to show how much there really is living in the sand on the sea floor.hat I begin with in training my gobies is frozen brine shrimp. These tend to settle to the bottom when added to the tank and sit on top of the sand. If you can get them to fall somewhere near where your gobies are sand sifting, they will eventually pick one up in a mouthful of sand.
