Whether you’re a lifetime lover of fish, or hope to work a pet fish into your current lifestyle, they can be beautiful additions to any home. Rainbow fish in particular are a popular type to keep as pets and, despite their ubiquity, the average pet parent may not know all that much about them.
Rainbow fish come in amazing iridescent colorations that change when the light reflects, be it a shiny silver or a blue and yellow combination. What you may not realize, though, is that “the color of a rainbowfish develops as the fish grows older, and is at its brightest when [the fish is] stressed, or when competing for the attention of a female,” said Claricoates. However, a stressed fish is not a happy or healthy fish.
Fun things to know about rainbow fish
Unlike some fish that are better off solo, rainbow fish can live with other fish, and prefer to be in schools of five or more, said Claricoates. While limiting male rainbow fish, as mentioned above, may seem unfortunate, the good news is that these fish do fairly well with others, including tetras, discus, guppies and other female rainbow fish.
Claricoates suggests providing your fish with several hiding spots in their tank, just in case things get stressful, and utilizing real or artificial plants (artificial plants are easier to maintain), and larger rocks that can be cleaned. The use of these components “makes the tank feel a bit more like a natural environment for these fish,” she said.
WHAT TO KNOW ABOUT FEEDING AQUARIUM FISH
In nature, fish eat whenever they are hungry and the food is available. If food sources are plentiful, they will eat several times a day. On the other hand, if food sources are scarce, they might go for days between meals. For this reason, fish are very opportunistic and will eat whenever they have a chance.
Regardless of one or two feedings, the key is to keep each feeding very small. Do Not overfeed your fish. Whenever in doubt, the best practice is to underfeed your fish. There are a lot of health concerns related to overfeeding your fish.
