Ask around for samples you'll be surprised . I have a few fish that would take months before they even try something different . Little-by-littleMy Mccoskers wrasse is the only fish in my tank that will eat all the frozen mix i put in. The rest just want mysis and lrs chunks ldk the point if mixing everything up when i see 50% of the food just floating around and the missile just shooting around eating it all up. They do like pellets and algae wafers.
