Crenicichla..... They are INDEED a cichlid. Come from South America, that particular species max. out at around 18"...but its not very common to get them that large. They are awesome fish, full of spunk, attitude, and color. There are tons of varieties to choose from, and even more species..... They are like nothing you have ever kept before. Totally redefine cichlids.....oh, they are highly predatory too...
