Exports from the Guiana Shield (Suriname, French Guiana, Guyana) is heavily restricted for multiple reasons- political, insufficient infrastructure, commercial restrictions, lack of preexisting industry since the 1900s, etc).
There's few people/companies with a permit/license and connections to import from the area in the US; larger wholesale retail operations like Carolina Aquatics and Segrest have brought in fish from the region before, as have smaller retail operations like Nationwide Aquatics and Aqua-Imports, but only sporadically. Unsure if there have been any commercial exports of wild ocellaris lately.
