The Apistogramma agassizi is known in the hobby as the Double Full Red Agassizi Cichlid which originates within the Amazon Basin of South America. This variation is tank-raised and has been bred for its brilliant red coloration within the dorsal and caudal fins. The body of these fish is elongated with a dark horizontal stripe. The dorsal fin extends almost the entire length of the body and is held low on the body with red outlines. These fish will change coloration depending on its mood.The Double Full Red Agassizi Cichlid should be kept in an aquarium that is 30 gallons minimum, with densely planted groupings. They require plenty of open swimming areas but also need hiding places. A fine gravel to sand substrate is recommended. Although a semi-aggressive fish, they are also timid and should not be housed with large, aggressive fish. They require good water conditions, and regular water changes are a must.
