Crested Gecko Mango MRP Superblend MEAL REPLACEMENT POWDER. Our Meal Replacement Powder (MRP) for all Fruit-Eating Geckos, such as Rhacodactylus, Phelsuma and Gekko. Also a great supplement for other species such as Anoles, Skinks, Chameleons and Iguanids. DIRECTIONS: Mix one part MRP with two parts water by volume as a starting point. The mixture may appear watery at first, but will thicken after several minutes. If separation occurs over time, use less water. As fed, MRP should have the consistency of ketchup. Feed geckos in the evening and remove uneaten MRP within 24 hours.
