Altum Angelfish crossed with Rio Nanay Angelfish, also known as Orinoco Angelfish, are locally bred and make a stunning addition to any aquarium. Growing up to 10 inches in height, these gentle and peaceful fish thrive in tanks of at least 50 gallons with water temperature between 78-84°F (25-29°C), pH levels between 6.0-7.0, and hardness levels between 2-4 dGH. Providing plants, driftwood, and hiding spots, along with regular water changes and a varied diet, ensures their optimal health and happiness.
