You can then start feeding them infusoria, newly hatched brine shrimp, crushed flakes, or commercial fry food.Īfter a month, try feeding the fry adult food broken into smaller pieces. The eggs will hatch in around 22–26 hours. This generally happens in the early morning. Remove the breeders after spawning, as captive black neon tetras tend to eat their eggs and fry. When spawning occurs, females will scatter hundreds of eggs onto the plants and substrate. While conditioning your breeding group, set the water temperature at 75° F, and maintain soft water with a hardness of 2–4 dGH and an acidity of 6 PH. After a few days, gradually raise the water temperature to 80° F to trigger spawning. Add fine-textured, live plants to dim the tank and provide the females with an area to spawn. A layer of mesh can also work, but make sure the holes are big enough to let eggs pass through but small enough to keep the breeding group out.Ĭondition your breeding group by feeding them live foods such as mosquito larvae and brine shrimp. Staining your water brown with tannin will also bring out the color of your black neon tetras, making them stand out.įilter the water with peat to encourage your black neon tetras to spawn. Replicate the black neon tetra’s heavily planted underwater environment by placing plants and decaying plant matter in your tank. The decaying plant matter will release tannin into the water, lowering its pH level and darkening it. Use a dark substrate covered with small pebbles to darken the water and mimic the river beds found in the black neon tetra’s habitat. These fish should be kept in a tank at least 20 inches long, 10 inches wide, and 10 inches high to allow them to swim around comfortably. Black neon tetras are small and reach lengths of up to 1.6 inches when fully grown, so we recommend at least a 10-gallon tank.īlack neon tetras are energetic shoaling fish, which means they need space to swim around as a school. The maximum number of fish in a tank should be equal to the tank’s capacity in gallons divided by the length of the fish in inches. To ensure your black neon tetras don’t suffer from loneliness, keep at least six of them together. This disease was first found in neon tetras and affects fish with a parasite that eats the muscles from the inside out once it reaches the intestinal tract.

DropsyĪnother disease that may affect black neon tetras is dropsy. Cycle your water to ensure you eliminate any last instances of the parasite in the tank. Quarantine any infected fish for a few weeks and treat them with over-the-counter ich medicine. Ich is caused by a parasite, Ichthyophthirius multifiliis, whose complex life cycle makes this disease hard to treat. Symptoms include small white dots on the body and gills of the fish, loss of appetite, and abnormal hiding behavior. One disease that may affect these fish is ich, which is one of the most common diseases encountered in tropical fish aquariums. You can prevent most fish diseases by adhering to the preferred water parameters of black neon tetras, keeping their tank clean, and quarantining new fish for 4–6 weeks before adding them to the main tank. Diseaseĭiseases in black neon tetras are most often brought on by unsatisfactory water conditions and infected fish. Replacing 30%–50% of the water in your tank every other week will keep your fish healthy and happy. These ailments are best prevented by ensuring your black neon tetras are swimming in clean water. The black neon tetra is susceptible to all the illnesses that affect other tropical fish, such as ich and dropsy. Flakes, frozen food, small live worms, and brine shrimps, and freeze-dried foods are all suitable for the omnivorous black neon tetra. These fish aren’t picky eaters and eat a variety of foods. ![]()
