Longfin danios are hardy, peaceful, and active schooling fish known for their elegant, elongated fins and vibrant stripes. They are a popular choice for community aquariums and are relatively easy to care for, making them suitable for both beginners and experienced aquarists. They are omnivores that need a varied diet and a well-planted tank with plenty of swimming space, plus a tight-fitting lid to prevent them from jumping out.
Appearance
Fins: The most notable feature is their long, flowing fins, which add a graceful and elegant look to the fish.
Body: They have a sleek, torpedo-shaped body with vibrant stripes, often running horizontally.
Color: While classic varieties have dark blue stripes on a silvery body, "assorted" or "golden" longfin danios can have a variety of colors, such as gold or yellow.
Size: They typically grow to be between 2 and 2.5 inches (5 to 6.5 cm) in length.
Temperament and social behavior
Peaceful: They are peaceful and social fish that are compatible with other small, non-aggressive species.
Schooling: They are schooling fish and should be kept in groups of six or more to prevent fin-nipping and to ensure they feel secure.
Active: They are active swimmers that add a dynamic energy to the aquarium.
Care requirements
Diet: They are omnivores and will accept a varied diet of flakes, pellets, frozen foods like bloodworms, and live foods.
Tank: A 10-gallon aquarium is a minimum size for a small group, but larger is better for more swimming space.
Water: They prefer well-oxygenated water with a temperature between 64−77∘𝐹(18−25∘𝐶) and a pH of 6.5−7.5.
Tank setup: A well-planted tank with open swimming areas is ideal.
Filtration: A good filtration system is needed to keep the water clean and well-oxygenated.
Lid: A tight-fitting lid is essential to prevent them from jumping out, as they are prodigious jumpers.
