I use it , The turtles love it TURTLE BRITTLE : : O.K. One day I was thinking about the Tennessee Aquarium, which is here in Chattanooga TN where I live. It is the largest freshwater aquarium in the United States and has an extensive turtle exhibit. I began wondering what they feed their turtles so I called them and they gave me the name of their head vet. Dr. Keller out of Chattanooga. When I contacted Dr. Keller he told me they feed their turtles Turtle Brittle and gave me the information needed to buy my own. He said that this was a complete and balanced diet developed for zoos and aquariums. He does recommend a variety of treats such as feeder fish, worms and crickets to help keep them active and interested. : : Not only is Turtle Brittle recommended by the Tennessee Aquarium but also by the Atlanta Zoo and the Atlanta Herpetological Society and the Knoxville Zoo. These are the ones I know of specifically. But Dr. Keller told me that all of the zoos and aquariums he has dealings with use turtle brittle also. If you have turtles less then 2 inches they also have Frog Brittle which is the same thing but small enough for the little guys. Or you can do like I do for my three youngest turtles. I just break it up a little bit. They all love it. : : Ingredients:::: fish meal, meat meal, soybean meal, corn meal, wheat flour, dried yeast, distilled soluble, whey, wheat germ meal, salt, vitamin supplements- diacalcium phosphate, protein minimum 44%, crude fiber maximum 2 % , : : ash maximum 11%, fat minimum 6%. : : Vitamin Content:::::: vitamin A- 14,000 IU per kg, Vitamin D- 5000 IU per kg, Thiamine-4.0 mg per kg, Vitamin B12-0.04 mg per kg, Folic Acid- 1.5 mg per kg, Niacin- 60.0 mg per kg, chlorine-1550 mg per kg, calcium 2.0%, phosphorus 1.6 %, Sodium Chloride 1.2 %, Magnesium 2 %, Linoleic Acid 2.8%, Iron- 300 mg per kg, Copper-10 mg per kg, Cobalt- 2.2 mg per kg, Manganese-9.0 mg per kg, Zinc – 100 mg per kg, Iodine- 48 mg per kg, Pyridoxine-8.8 mg per kg. : : Where to get it ::::::::::::Nasco : : 901 Janesville Ave. : : Fort Atkinson, Wis. 53538 : : 1-800-558-9595 : : Turtle Brittle : : Item # SB13523LM : : 5lb bag $ 12.00 : : $4.00 shipping : : Jimmy ( Draybar)
