Alenquer is a region along the amazon that is know for producing some of the nicest wild red discus. Cuipeua is a smaller area in the Alenquer region that has some of the sought after wild red discus. Now comes the problem. There are domestic discus sold under the name of Alenquer which are not wild discus from the Alenquer region but are a domestically bred discus that was bred to look like a wild discus. The one pictured above is a wild red from the Alenquer region. You need to also be aware that not all wild reds from the Alenquer region are going to exhibit the red coloring or halo that you like so much. Some will be more of a brown and some more of a orange/yellow. The more red the more expensive. Your search is at a bad time though because the wild discus season has ended and not many will have any available. You will also find it difficult to find them at 3 to 4". Wilds are usually marketed in the 5" or larger range. Uncle Sams Discus just listed some 4" Red Alenquer that I believe may be F1's. http://forum.simplydiscus.com/showth...Price-List-*** You can ask Darwin and he will let you know. My favorite pair right now is a F1 pair from them that I got a couple of months ago.
Mine have more pattern and striations than the one you have pictured above but wild alenquer reds range from solid to royal or fully striated.
