sandtiger;1176139; said:You can only breed oscars with other Astronotus species and besides the oscar there is only one other confimed species. Astronotus crassipinnis. Their next closest relatives belong to the Chaetobranchus genus and it's likely they can cross with them as well. I have never seen these fish in the hobby. There are currently two Chaetobranchus species classified.
Chaetobranchus semifasciatus
