My sakura goby is looking a bit skinny. I've had him for about 8 months, he did have a friend but I think the multiple house moves took their toll. I fed the tank bloodworms this evening, and he had at least 3 (despite the best efforts of the corys to steal) but he's a lot more trim than he used to be. I can't hand-feed, because I can't get near the poor thing, is there anything else I should be doing?
