I am doin a straight suriname biotope I need to know what species to start collecting, don't worry about the size of the fish as they get bigger the tanks get bigger, finally ending up in a pond
The one ray that stands out right off the top is called Boesemani, But you won't find one here in the states. The only ones imported in North America that I am aware of were by Oliver Lucanus of Below Water out of Canada. There were only a few and the price tag was quite high. GL on your search but I fear it will be futile where rays are concerned.
