Heres some info on the differences between the blood/super reds and the chili reds. I have a chili myself I call him " CHILZZ "
( Not my Chili, but a really nice pic of a Chili I'd like to share with ya'll )
Enjoy!
The Chili Red and Blood Red are both originated from two famous waters in Western Kalimantan, Indonesia called the River Kapuas and Lake Sentarum. Lake Sentarum, consisting of many smaller lakes interlinked between each other, is at one end of River Kapuas. These waters are covered by the thick Peat Forest which provides a very primitive environment for these Jurassic fishes, but with its naturally occurring minerals, blackwater and abundance of food source produce very positive effects on the colors of this particular variety of Asian Arowana. Also the vast areas of red arowanas habitat may be the reason behind the variations within the red arowana variety. Some seem to have broader body, steeper spoonheads, greater red intensity and heavier base colors than others, just for example. And, it is because of such differences in appearance, the early dealers in Indonesia created another two general terms for two main groups of red-turning arowanas found in that region. They are Chili Red and Blood Red. The names Chili and Blood were given because of their difference in red intensity, Chili Red has a chili color while Blood Red has a red color that looks like blood color. Apart from colors, Chili Red and Blood Red are also different in terms of shape. While Chili Red is broader in shape, Blood Red is longer and slimmer. This broadness can be seen between the back and the bottom of the body of a Chili Red that is both thick and wide. This wideness extends all the way backward to tail of the fish rather than one that the usual tapering downwards to the tail, which belongs to that of a Blood Red. This difference in shape together with its thick frame scales, spoonhead and intensified red color scales has made the Chili Red look more massive, forceful, well-balanced and prosperous-looking.
The Chili Red also has large red-colored eyes and a diamond-shaped tail while the Blood Red has whiter and smaller eyes and a big wide-opened fan-shaped tail. Chili Reds has eyes so big that sometimes the edges of the eyes actually touch the top of the head and the lower jaws. The tail of Chili Red is obvious diamond-shaped which can be large and outward-extending as well. The Blood Red on the other hand, has much smaller eyes that look somewhat normal and a rounder, widely spread tail that is simply beautiful. These characteristics are obvious even when the fish is young, so it is possible to spot a Chili Red or Blood Red when young. Apart from the above, a personal opinion from us is that the scales of Chili Reds have more obvious green cores and have heavier metallic shines while Blood Red have shines that is shinier and tends to resemble that of a Cross-back Golden when young. Also, the shape of a young Blood Red seems rounder as compared to Chili Reds.
