Eliceo is a member of the Matapi and Yucuna tribes, the only tribes in the Colombian Amazon that use their tribal names also as last names. He spent his first years growing up in a tribal village between the Miriti Parana River and the Caquetá river, once the tribal homelands of his family, in the Pedrera region of the Colombian Amazon. He learned the cultural practices, customs and traditions of his tribe as well as hunting, fishing, and the basics of survival in the Amazon jungles. In 1999, when Eliceo was 11 years old, his family moved to the city of Leticia looking for greater opportunities for education and work.

After receiving his official tour guiding certificate in 2008 and graduating in Ecotourism and community development in 2010, Eliceo has worked as a tour guide and translator for various agencies in Colombia, specializing in the Amazon region.
