I added a pink spotted goby to my display tank a couple of days ago. Right now I have a 2 inch huma, maroon clown(not aggressive) and a yellowtail damsel(not aggressive). He stays in his cave probably still getting use to his new surroundings. My huma and maroon clown always hog the food at feedings. I am worried if my pink spotted goby will not get any food. At night should I place some brine shrimp by his cave or will he eventually get more aggressive during feeding times? Also should I get him a pistol shrimp? I have a 75 gallon tank. thanks
