Origin South America; Orinoco eartheaters are to be found in the Rio Orinoco, primarily in Colombia and Venezuela. Sexing Virtually impossible to sex, if Orinoco eartheaters are being kept for breeding purposes, it is best to purchase a group of juveniles. Breeding Pits are made in the substrate ready for the eggs. When the eggs are laid, the female will tend the nest while the male will defend the territory very aggressively. After 10 days the fry should be free swimming and can be fed on Infusoria initially. A few days later they should accept newly hatched brine shrimp. Lifespan The expected life span for Biotodoma wavrini is 3-5 years. Short description Orinoco eartheaters are quite rare in the aquarium hobby. As juveniles, they may look a bit drab but they will colour up beautifully as adults. Sand must be used as a substrate for the tank as they sift through this looking for food.
