No, capapretum and filamentosum are very different fish. They were only recognized as a separate species recently. I've posted a few photos and articles about my old capa. A true real filamentosum are rare and very hard to find and last I saw were $1000 for a 3" or so.
Re-read the post in the context of "regardless if is a capa or fila, you have a nice fish at a good price." Thats what was meant by "all the same" not that they are the same fish. Poor English I guess.
The most telling difference at this size is the spots. True filamentosum have spots that are smaller than the eye, capapretum has spots the same size as the eye or larger.
Both your fish and the one on Aquascape are capapretum.
