For whatever unknown reason, I dropped a tiny piece of baked chicken into my shrimp tank today, and they were all over it until it was gone! they were working that chicken so fast little pieces were flying everywhere and got stuck in the java moss and now they are eating the little chicken bits out of the moss. Now I feel like I haven't been feeding them a varied enough diet. They get algae wafers, zucchini and now chicken. What else should I give them?
