As a fish owner, you’re going to work to keep them safe and provide them with as much food as they need. It’s common for hatchetfish to live up to five years in a fish tank, but they might not live so long in the wild.

A fish might only live a few years in the wild. The exact amount of time the fish will survive will depend on various factors.

How to Help Fish Live Longer

To get your fish to live longer it’s important to focus on keeping the water quality high. Test the water regularly using pH balance testing kits.

If the balance is off you can adjust things to keep it in line. You also need to clean the tank regularly and do water changes periodically.

Feed the hatchetfish properly and give them high-quality food. Make sure to feed them enough without overfeeding them as too much food can lead to health issues.

You also want to keep them in groups since hatchetfish are shoaling fish. Ideally, you want to keep six of them in the tank.

Final Thoughts

Do your best to help your hatchetfish live for as long as possible. Most hatchetfish have the potential to live for five years or slightly longer.

Some of them commonly die after two or three years, but you can get better results by providing the fish with excellent care. Simply commit yourself to maintain the tank well and you should be able to enjoy these fish for many years.
