After 2 days of not eating, my RA was back to normal tonight. I fed a few large cubes (Marine Cuisine and Emeral Entree) tonight. She doesn't pick at the cubes as much as my Dogface Puffer and Naso. Instead, she usually picks at my fingers while I hold the cubes under the water's surface. She prefers to eat the small individual, floating pieces of food instead of attacking the whole frozen cube. Anyway, she seems back to normal, so I'm happy again.
