GARGOYLE said:your title is a bit confusing, but between reds and caribe, the biggest difference visually is the black humeral spot the caribes have. And with time you will also notice the aggresiveness of the caribes. Mine attack food first and eat the most. The reds will coming clean up once the mess is over. But all are different so agrresiveness will be greater in some. I just threw in a whole beefheart and in a minute they took it all out. I have 13 caribe and 3 reds.
