So, I guess I've gotten quite lucky with my Marine Betta. Not only does she not hide anymore (is always out when actinics are on; she does hide when MHs are blasting), but she eats like a pig. I give her a piece of silver-sides every 4-5 days (she starts grabbing it from the tweezers as I lower them into the tank), but she also grabs and eats the stuff I feed the other fish - mysis, freeze-dried brine shrimp soaked in vitamins, and formula one. And she's still always out, opening her mouth, asking for food. How much is too much?! :scratchch
