Common Name: Redtail Splitfin
Native to the Upper Rio Compostela and Lower Rio Grande de Santiago basins in Mexico, Xenotoca eiseni is a livebearer inhabiting streams and springs. It prefers warm, hard, slow-moving water. This is a herbivore. The diet consists of various algae and plant material with minimal animal protein. The digestive tracks of these fish are longer than some other goodeids in order to aide in the digestive process and breakdown of fibrous foods. High fiber foods are necessary in eliminating waste in the intestinal track. It is important not to give high protein foods. Examples of foods to feed are spirulina algae, nori, unsalted French-cut green beans and blanched vegetables. Small amounts of baby brine shrimp can be given but NO bloodworms.
