There seems to be a lot of confusion in the naming conventions of Asian aro's. As Earl mentioned, there are indeed two types of red arowana --blood and chili-- which are really just variants of the same species from different parts of Indonesia. Since there is no evidence that either exist naturally in the wild anymore, and lines have been crossed and re-crossed so many times by breeders, your chances of getting a pure chili or blood are nil. With all the gene crossing that has happened in an attempt to produce the most vivid reds, it is very possible for a blood red aro to develop from chili parents, and vice versa. Add to the fact that arowana colour can be influenced by external factors like water parameters, lighting, food, etc, there is not much of a guarantee that the juvenile red aro you own will become either type until it is full developed.
All the other red arowana terms floating around out there -- "super red," "VIP red,"Violet Fusion Super Red," etc etc -- are all just marketing names given to the above mentioned red arowanas.
Buy the red from a reputable farm and inspect it for all signs of good health. These fish are not for the bang-wagon hobbyist-- it takes YEARS of nurturing for your fish to reach its full colour potential.
