![]() Keep the fish apart while you set up a separate 10-gallon breeding tank with a sponge filter and a sandy substrate, and establish a water temperature of 71–80☏. Choose a healthy adult male and female zebra danio.Zebra danios are egg layers and lay hundreds of eggs at a time.įor the best chance of success, follow the steps below for breeding zebra danios: The fish reach sexual maturity at three months old. Zebra danios are easy, beginner-friendly fish to breed. If you notice signs of ich, quarantine the affected fish and increase the water temperature to 77☏ to speed up the lifespan of the parasite. Symptoms of ich include white spots on the fish’s body, lethargy, and flashing, where the fish rubs its body on rough surfaces. Ich is a parasitic skin disease caused by Ichthyophthirius multifiliis. However, the fish are prone to several common freshwater diseases, including: Ich There are no diseases that specifically affect zebra danios. Maintaining optimum water parameters greatly reduces the risk of conflict and disease in the tank. Poor tank conditions can stress zebra danios and cause their color to fade. GloFish zebra danios require a blue light to show off the fish's neon colors Water heater: Yes, if the fish are housed in a location where ambient temperatures fall below 60☏ The ideal tank conditions for a zebra danio are: Water type: Medium-hard, slow-flowing freshwater Tank size: Minimum 10 gallons, plus 2 gallons per extra fish Water temperature: 64–77☏ Substrate: Soft, fine sand Tank setup: Plants, smooth rocks, caves Acidity: 6.8–8.0 pH Water hardness: 5–19 dGH Filter: Yes, to provide a current that replicates the slow-flowing waters in the zebra danio's habitat Pump: Yes, to provide oxygen and water movement Bubbler: Not necessary, but can supplement an air pump to further oxygenate the water Lighting: Yes, standard aquarium lighting is needed for plant growth and to mimic the day-to-night cycle. Mimic the zebra danio’s habitat in captivity with suitable tank decorations and the right water parameters. This natural habitat is tropical, densely vegetated, and packed with smooth pebbles. In the wild, zebra danios live in slow-flowing freshwater lakes and streams in South Asia. Replicate the danio’s wild habitat in captivity and feed them an omnivorous diet to ensure they are happy and healthy in the tank. Zebra Danio Care & Tank RequirementsĬaring for zebra danios is easy because they’ll eat almost anything. Although the fish are peaceful, they’re known fin-nippers, especially when housed with slow-moving, long-finned fish. ![]() ![]() Zebra danios have hierarchical systems of dominance within their shoals, established through play-fighting and non-aggressive chasing. ![]() Getting the balance right is important - too few zebra danios can cause stress, while too many zebra danios can cause hyperactivity and territorial behavior. Quarantine new fish for a few days before adding them to the aquarium.Ĭatching a disease outbreak – like fin rot or ich – early on means you only need to treat a few infected fish rather than all the fish in your tank.As shoaling fish, zebra danios are bravest in groups of five or more. If you add new substrate or plants, thoroughly clean these before placing them in the tank. New additions to the tank can introduce disease. Stressed fish are more disease-prone, but if the tank conditions mimic the fish’s natural habitat and they eat a well-balanced, varied diet, leopard danios will thrive. Leopard danios are resilient, and if your tank is well-maintained, common fish diseases aren’t usually a problem. Advertisements Water type: Freshwater Tank size: Minimum 10 gallons, but 20 gallons is preferred Water temperature: 64–75✯ Substrate: Sand or dark, fine gravel Tank setup: Plants Acidity: 6.0–8.0 pH Water hardness: 2–20 dGH Filter: Yes, to help keep the tank’s water clean and remove debris, nitrates, and ammonia Water movement: Yes, to help keep the tank’s water clean and remove debris, nitrates, and ammonia Lighting: Subdued or moderate/normal lightingĭiseaseWhile a school of leopard danios can be kept in a nano or small tank, they thrive in a 20-gallon aquarium where there’s plenty of space for these lively fish to swim.
