I'm having trouble feeding my goby b/c the damsels always eat all the food before he can get any. He eats flake food when it gets to him , but thats only little pieces that made it to the floor and past the damsels. I think today might be the damsels last day in my tank! Anyone have any other suggestions? I was thinking of a food that sunk pretty quick so I could spot place it, any ideas?
