Okay, I always feed my chalices brine shrimp and they eat the stuff up like they love it. So why are they expelling it an hour or two after ingesting? Are the brine shrimp and other solid foods too much for them to digest? I'm still getting great growth and colors but if they are expelling the food that quick after feeding, it's my belief that they aren't getting many nutrients from it. I'm thinking of moving away from spot feeding and just feeding the system as a whole. What are your ideas and thoughts?
