Oh yeah. I've got a 50 and a 45. And a couple of twenties and fives with tropicals. It's definitely a bit of work to keep them clean. They tend to make a pretty good size mess. Worse than tropicals. But then they tend to be much bigger fish so that makes sense. Right now I've got a 45 with a hybrid blood parrot and a few mixed Africans that I raised from a small size. They're all about four or five inches or larger. The parot is as big as my palm. For their demeanor they're definitely one of my favorite cichlids. They would be fairly territorial amongst themselves. But in the 45 with the other mixed Africans they tend to leave him alone and he tends to leave them alone and is just the friendliest little guy. When I'm cleaning the tank or doing anything he's right there by my hand.
