Danios may have small bouts of fin-nipping with any long-finned tank mates but this should not be too serious. However, if keeping with fancy goldfish, try to avoid slow-swimming longer-finned varieties.
Leopard Danios have a very small mouth, so any damage will be fairly limited and is unlikely to persist. The the size of the food should reflect this, so feed fine granules, such as Betta or Fry food granules.
In the wild, the danio's are found in along the surface of small, clear rivers and hill streams. Leopard Danio's are a very hardy fish that like to shoal together which makes them great for beginners. They are suitable for indoor cold/temperate water tanks also.
