I have split this post from the topic in the species index, which is primarily for informational posts rather than questions. This specific question also brings up a problem of resolving two threads in the species index section that may be talking about the same thing. Because of that, it seemed more appropriate to have the discussion in the cichlids forum and then for the species section to be amended appropriately (rather than discussing in the index and having to potentially clean it up threads afterwards). There are two relevant threads:
Gold Saum - http/www.fishforums.net/index.php?/topic/412823-gold-saum-andinoacara-rivulatus/
Green Terror - http/www.fishforums.net/index.php?/topic/138802-green-terror/
Neither one answers the question above as to why the two are different. I am not a cichlid person, but out of interest I went looking to see whether those threads should be merged and read conflicting info. From the standpoint of the species index and the question in the post above, there are two issues in addition to the question above:
1. Are the two species adressed actually taxonomically distinct? (This is what I just read ambiguous info on - one source saying yes and another saying no)
2. Is the Green Terror thread in need of overhauling or merging with the Gold Saum thread if the two threads are talking about the same animal?
