I just added this product to their daily staple...After seeing the first feeding though, I'm thinking of feeding only twice a week to them....They were chewing on the sticks, but spitting the stuff out...It's their first time trying this stuff too...I want them to like this stuff just because it's also a color enhacer...The shoal chows down greedily on krill, shrimp, and Hikari Bio-Gold...I saw a batch of deep red mollies at the lfs today, is it true the feeder's red coloration will also enhance the predator's???I'm against feeders, but just curious....
