Who has Crenicichla?

Just as the title says. Who has Crenicichla and what kind? I have kept a few species including C. compressiceps, C. sp. venezuela, and C. proteus. I now only have C. proteus and it is my favorite fish in my tanks. So I was just wondering if any AC people keep these little beasties. (well I guess that some, like the vens, aren't so little)

Yes, they can be a little scrapy every at times, but I love em. And there are so many different species that there will always be a rare new Crenicichla, if rare is your game. The species I kept were not rare by all means, but they were all still some of my all time favorite fish.
