Keeping zebra fish at home is a fun and rewarding hobby. When cared for properly, zebrafish can live for up to six years. These bright and entertaining fish are easy to maintain and make excellent pets for beginners. They are also relatively inexpensive to buy, feed, and house. What’s more, they grow to around 10 cm in length, making them a perfect pet for smaller aquariums as well as larger ones. However, when it comes to keeping zebrafish at home there are some things you need to bear in mind. While they are generally quite hardy, these little guys have specific husbandry requirements that must be followed if you want your pets to grow happy and healthy.
What is a Zebra Fish?
Zebrafish are freshwater tropical fish native to Southeast Asia. They are some of the most commonly kept aquarium fish and come in a vast range of colors. The wild-type zebrafish is a black fish with a white stripe down each side. However, there are now many different varieties of zebrafish, including red and yellow types. Some varieties have multiple colors, such as the multi-coloured zebrafish (AKA half-moons). The zebrafish has long been used by scientists and researchers. The fish is particularly easy to breed in large numbers, making it an ideal choice for laboratories. The zebrafish genome has been fully sequenced, meaning scientists are better able to understand the fish and how it ticks. This has allowed researchers to develop new treatments and cures for diseases as well as explore potential cures for human ailments.
Zebra Fish Requirements
Like all fish, zebrafish require clean water, a suitable temperature, and a nutritious diet. It’s also beneficial to include some additional enrichment items in the tank to keep your fish happy and healthy. Zebrafish are tropical fish and need a water temperature of between 22 and 26 degrees Celsius. You can keep your zebra fish at a lower temperature, but they’ll be more active and you should provide them with more space to swim around. When it comes to water quality, zebra fish are slightly fussy. They like soft water with a neutral pH, though they can tolerate a slightly more basic pH (8-11). They also prefer clean water with minimal pollution and a low level of dissolved organics. To keep your water clean and healthy, there are a few factors to consider:
- Temperature: Keeping temperature consistent is key to keeping a healthy tank. If your water is too cold, your fish might not be able to digest their food, which could lead to health issues.
- pH: pH is a measure of the acidity of water. A pH of 7 is neutral. Anything lower is more basic, while a pH above 7 is more acidic.
- Ammonia: This is a harmful byproduct of decaying food in the aquarium. It’s important to keep ammonia levels low.
- Nitrite: Another byproduct of decomposing food. While lower than ammonia, you don’t want nitrite in your tank either.
- Nitrate: This is a byproduct of your fish’s natural biological process. It’s not harmful if kept at a low level. - Lighting: Plants need light to grow, and lighting can also help keep your water clean.
Zebrafish Tank Requirements
The size and shape of your zebra fish tank will depend on how many fish you want to keep, their growth rate, and their adult size. It is advisable to keep your zebrafish in a tank with a minimum length of 16 inches and a width of 10 inches (40 cm x 25 cm). You will also need the following equipment for a healthy and happy tank:
- A tank: Zebrafish are tropical fish and will not survive in cold water. You will need a tank that is kept at a consistent temperature.
- Filter: A filter will help keep your water clean and healthy and encourage bacterial growth. You will need to replace the filter regularly.
- Lighting: Plants will add to your tank’s aesthetic, but they also help keep it healthy. You can also use lighting to help you maintain a consistent light cycle.
- Deco: Decor-like plants, rocks, and driftwood can help your zebra fish feel at home. - Gravel - Gravel will help keep your tank clean by absorbing ammonia and nitrites.
The Tiny Fish That's Changing Modern Medicine
Zebrafish are omnivores and enjoy a wide variety of foods. They are most commonly fed commercial fish flakes, which contain a mixture of grains, seeds, and vitamins. You can also give your zebra fish live or frozen foods like brine shrimp, mosquito larvae, or bloodworms. Zebra fish can be fed a diet once a day. It’s best to feed them in the evening, as this will encourage them to rest and reduce stress. Feeding your fish twice per day will result in them feeling more active, leading to more swimming around the tank and higher levels of stress. Zebrafish are very sensitive to changes in their environment. If your fish are eating twice per day, you may start to notice changes in their behavior, such as increased swimming or aggression. If you notice any of these behaviors, try feeding your fish once a day instead.
