You haven't seen a male Halfmoon Dragon guppy in all its splendor like this before. This is a peaceful and hardy livebearer fish perfect for any hobbyist. It is a small fish that does well in a nano aquarium. Also, it can do well in bigger tanks with other fish. Just make sure that their tank mates are of the same temperament. Some good examples are bettas, corry cats, danios/minnows, and other livebearers. They can be added with angelfish and discus as well just make sure they are not breeding. You wouldn't want them to become aggressive towards your new guppy.
