I feed frozen (thawed) brine and mysis along with many other things. You know what they say...variety is the spice of life! I always soak my thawed food in Zoe and/or garlic elixir preferrably overnight. The fish will ALWAYS go for the "candy" first, but do manage to clean most of it up no matter what I've served. The only thing that goes over like a lead balloon is squid. I have given up feeding that and now just share it with Mr. Mantis who lives in the refugium and eats anything and everything that comes his way!
I have a coral beauty in my FOWLR that will not eat anything. I have no idea how he is sustaining himself, but he's fat and happy looking. He will not even LOOK at my offerings of brine (live or previously frozen) or any type of algae except what little bit is naturally occuring on the walls and liverock in the tank. Any ideas about this little fella?
