The Neon Swordtail is an aquarium fish that is notoriously easy to care for. They have a peaceful temperament and are omnivores that can be fed flaked foods, algae, bloodworms, tubifex, and brine shrimp. They only grow to about 4" in length, so an aquarium of at least 30 gallons with a tight lid to keep them from jumping out is recommended. Water conditions of 64-82° F, pH 7.0-8.3, KH 12-30 are ideal. These fish make great tankmates with most other community fish. One thing to note though is that keeping two males in a small aquarium can lead to arguments between the two.
