The husbandry of all forms of Guianacara species in the aquarium is identical. According to López-Fernández et al. (2006), all known species prefer clear, soft, and slightly acidic waters with a substrate of large rocks intermixed with sandy patches often at sites with relatively fast current in the wild, so they should be housed accordingly in the aquarium. Their requirements in the aquarium are few, and they can hold their own in a mixed rowdy medium-sized cichlid community tank. I have seen large bull males of G. sphenozona reach lengths of over 6 inches (with a large blocky head), but they will spawn at 3 inches. Females are typically two-thirds or less the size of males.
