Cold waters may make them more prone to diseases. Zebra danios are also adaptable and resilient, capable of withstanding impressive temperature variations, although not for long. These are peaceful but energetic fish that can share space with many species similar in size and temperament. Your typical danio fish can reach 2 inches at most, although most specimens will remain smaller than that.
