I feed my 2 clowns once a day in the evening they look forward to it. Mine get "Formula 1" and sometimes some brine shrimp I dice up little bite size pieces that they can swallow whole. I dont know how accurate this is but I read somewhere that brine alone doesnt have all the nutrients in it to sustain a fish for a long time. Again I only remember seeing this on another post, I have no idea if thats true or not.
