And now, what I learned today: basal fish are basal for a reason. They are not outdated and primitive, they're just doing something right and have been for awhile. If the convict family tree was like ours, convicts would be like us evolutionarily. They are that advanced on that tree. Cryptoheros on the other hand, would be like gibbons on our evolutionary tree. Meanwhile, my male cutteri beat up my full grown pair of Honduran red points today. Both of them, in four hours. My normally aggressive male, shredded, his mate, a little less so. This isn't the first time my male cutteri has beat the living hell out of something. When I first got him his mate, he beat her up. She was in a hospital tank for about a month. When I moved them to the 29, he beat up my male nanolutea and took his mate. They spawned twice. Then I guess the female nanolutea got tired of being beaten up by the male cutteri after losing a batch of eggs so she paired back up with the male nanolutea, I moved them to their own tank, and they currently have a batch of eggs.
I guess cutteri, after a few hundred thousand years of evolution, learned how to beat the hell out of any newcomers. Or do the same if they themselves are the newcomers. It's like that Bruce Lee quote that pretty much goes "try everything, use only what works". I guess cutteri, and other basal species of fish, go off of that. Maybe we can learn from this in our rapid advancements, that maybe instead of pushing forward all the time, maybe we should look back a bit every once in awhile, maybe we'll find something back there to make something new even better. This one's less of an intelligence thing but you get where it's going.
Makes you think...
