I have acans, ricordea mushrooms, hammer, toadstool, duncan, trumpet, anemone, some polyps and a few others. I have two gobies and two shrimps so I feed them a little bit of brine and mysis shrimp twice a day. Not sure if that's good enough, but the reason I was thinking about feeding them salmon is because I have some fresh salmon that I'm not going to cook or eat.
