SxK 4/22/11.

These fish were just fed bloodworms that have sank to the bottom. In this video I try to capture sand sifting behavior. If you watch close a few of the fish demonstrate this behavior but I caught them after they had eaten a bunch and are in the act of chewing. There are times when all of the fish are intensively sifting. I think that providing a sand substrate is essential for goldfish health. It allows for the sifting behavior which in my opinion keeps stress low. More importantly, the sand acts as ruffage for good digestion.
