Last December my wife and I spent a week in Costa Rica on the north west pacific coast (Guanacaste) and we spent a lot of time on the Rio Tempisque river, and a few other rivers. The water was very murky, and it seemed like a lot of the fisher men were catching a lot of catfish. There were a lot of crocs too, so we spent more time on a nice sized boat or in areas where people told us it was safe
My questions are:
1. What cichlids are commonly found in Guanacaste?
2. What would be the typical bio-type? Some areas seem to have a muddy-clay substrait and some seem to be rocky/sandy. Would black sand be found in areas near volcanos? It seems to be the caase on the coast with black sand beaches, black/white sand beaches, and white sand beaches.
Costa Rica is one of the most beautiful countries I have ever been to and the people are wonderful as well. I highly recomend going in December between the wet and dry seasons.
