Dwarf Neon Rainbowfish are classic , quite equally adapted to eating both animal and plant matter in the wild. In captivity they should be fed a high quality flake or pelleted food to maintain good health. Buy foods frequently and in small amounts, as the nutritional value of these products quickly deteriorates. Another large chunk of their diet should be live foods like brine shrimp, bloodworms, and tubifex worms. They also enjoy plant matter, so if you don't have any live plants for them to nibble on, consider giving them blanched lettuce leaves or a plant based food from time to time. Feed these fish several times a day and only what they can consume in under 5 minutes.

Most Rainbows are prone to skin flukes, parasitic infestations (protozoa, worms, etc.), ichthyobodo infection, parasitic infestations (protozoa, worms, etc.), bacterial infections (general), and bacterial disease. Goiters can be common in these fish in aquariums and normally caused from diet deficiencies, usually from not enough iodine.Rainbowfish are extremely hardy and disease is not usually a problem in a well maintained aquarium. That being said there is no guarantee that you won't have to deal with health problems or disease. Remember anything you add to your tank can bring disease to your tank. Not only other fish but plants, substrate, and decorations can harbor bacteria. Take great care and make sure to properly clean or quarantine anything that you add to an established tank so not to upset the balance.A good thing about rainbow fish is that due to their resilience, an outbreak of disease can often be limited to just one or a few fishes if you deal with it at an early stage. When keeping more sensitive types of fish, it is common for all fishes to be infected even before the first warning signs can be noticed. The best way to proactively prevent disease is to give your Rainbow fish the proper environment and give them a well balanced diet. The closer to their natural habitat the less stress the fish will have, making them healthier and happy. Stressed fish are more likely to acquire disease.For information about freshwater fish diseases and illnesses, see . This is a great source for information on disease and treatments. It is recommended to read up on the common tank diseases. Knowing the signs and catching and treating them early makes a huge difference. Rainbow fish are very resilient.
Rainbow Fish Activities - DLTK-Teach
Red Rainbowfish do fine in a community aquarium of similarly sized fish, but do exceptionally well in a geographical tank stocked with other rainbowfish. Although generally non-aggressive, overly aggressive or very shy tank mates will make bullies out of them. Mix them with other playful but good natured fish for best results. If in a tank with both other males and females, the males will occupy themselves by displaying their brightest and best red colors and flaring their fins. When males are displaying, you may notice some chasing between rainbowfish, but this is rarely a concern unless a fish is injured, has nowhere to hide, or is constantly harassed (usually a result of one of the first two).
