A great supplementary food to help boost the color, health, immune systems, breeding and growth in all of those fish with small to medium sized mouths. Discus, angels, tetras, livebearers, rainbows, dwarf cichlids will all love this sinking crumble food. A great food to feed along side Xtreme Crave Flakes, Xtreme Krill Flakes, Xtreme Spirulina Flakes and Xtreme Wrigglers. This is a high protein food, so a little goes a long way when feeding. Xtreme offers this crumble food in their new resealable zipper pouches – easy to get to the food with your fingers and easy to seal the pouch after every use to help keep the fish food fresh and dry. The pouches even have a clear bottom gusset, making it easy to see the food inside.
