Angels are a small genus of freshwater fish from the family Cichlidae. All Angels originate from the Amazon Basin, Orinoco Basin and various rivers in the Guiana Shield in tropical South America.
Angelfish are one of the most popular aquarium fish and they certainly add a lot of grace and beauty to a tank. These fish are often thought of as community fish, meaning they can live with a variety of other tropical species. While this is true when they’re young, angels become more territorial and aggressive as they mature.
Always keep angels in the cleanest, largest size tank you can support, and make sure you have a good filtration system that doesn’t create excessive currents in the water since angels aren’t the most agile swimmers. The right water conditions can also lessen stress on your angels and keep them healthier and happier.
