24¼ × 12½ × 12¾ in outsideHow to keep glowlight danios
Glowlight danios are small, active danios with a bright orange band and blue-black bars, closely related to the zebra danio. Keep six or more in a 15 gallon or larger tank with room to swim and a lid; they like cooler water (66 to 75 °F) than most tropical fish, which makes them good company for white clouds and other cool-water fish.
Diet: Omnivore: flakes, micro pellets, small frozen foods. Fish food types compared · how often to feed.
Where they swim: Middle of the tank.

Common glowlight danio problems
- They jump; keep a lid on.
- Kept warm all year they fade and live shorter lives.
Test the water first whenever fish look unwell: see what your readings mean, then match the symptom. For disease, a vet who treats fish can diagnose it and advise treatment.
