It is hypselacara temporalis 100%. when you piss them off / stress them out they get that colouration. Some are dark purple/red with some dark green, others are light emerald green with little red. I think it depends entirely on collection point. I have had some light ones, and some dark ones. Right now I have a 7" male that is dark purple red and has show quality fins. Mine is very very territorial and aggressive but most other chocolates I have kept are peaceful. Either way he only chases so there is more than enough room in my 225. He really dislikes my giant gourami.
All I can say is wow, there are some real retards out there that it took all the way to the 2nd page for someone to guess it was a chocolate cichlid. Severum hybrid? really?
