Hi Hip,
As far as I knew, the Red Oscar is the most similar to the naturally occurring Oscar. Those with a mostly greenish brown(could be reddish-brown) color, and a large red streak on its underbelly. There are of course variations due to selective breeding, long fins which I think is most easily attributed to "selective" breeding and not natural variation. I do find the variations interesting, but what really interests me is if there is any intelligence difference between the varieties. I've only had one albino but it really seemed smarter than my tigers. Unfortunately testing intelligence is hard enough with humans

O yea, been slow on the replies last couple days, been sick again, later
