Hi I am going to be attemping a 40 gallon biotope with fish from west of the andes in Colombia instead of a blackwater dwarf pike biotope. I have a pair of A. Biseratus and 11 emperor tetras. I was looking to see if there were plecos and corydoras in the area but there is so little information on the area online. Does anyone know of any if not I'll probably make it a Colombian biotope.
