How to Help Kuhli Loaches Live Longer

There are a number of different things you can do to help your kuhli loaches thrive. You can keep them in good health by focusing on the basics.

Below, you’ll learn about the specific things you need to do to keep these fish alive for as long as possible. If you follow this advice it’ll be easier to keep them alive for ten years or more.

1 – Focus on Water Quality

Focusing on water quality is smart when you want the fish to stay alive and healthy. You need to make sure that you get the water parameters right.

Monitor the pH balance of the tank to ensure that it stays between 5.5 and 6.5. You can test the water using a pH balance testing kit every so often.

Use a heater to keep the water temperature between 75 degrees Fahrenheit and 86 degrees Fahrenheit. The heater helps to avoid exposing the kuhli loaches to water temperature fluctuations.

Remember that these fish need you to keep the tank clean. Do your best to do weekly water changes and focus on tank maintenance.

If you put in the effort, it should be easy to maintain high water quality. Your kuhli loaches will be far less likely to get sick and die early if the water quality is consistently excellent.

2 – The Tank Size Matters

Getting the right tank size is important when you’re trying to keep the kuhli loaches in good health. Like many types of fish, kuhli loaches don’t like being put in cramped tanks.

It’s not wise to try to force kuhli loaches to live in small tanks. Generally, you want to have at least 20 gallons of space for these fish.

However, it’s better to go with an even larger tank. You can keep three kuhli loaches in a 29-gallon tank comfortably.

If you want to keep more of them you can buy an even bigger tank. Going with a bigger tank makes the fish happier overall.

It also makes it easier to keep the fish tank clean. Smaller tanks get dirty faster and can be more difficult to maintain.

3 – Kuhli Loaches Need Friends

These fish need to be kept in appropriately-sized groups. While they aren’t schooling fish, they are fish that like to live in groups.

You should keep no fewer than three kuhli loaches in the tank. If you want to get the best results, it’d be better to go with six or more kuhli loaches.

These fish feel much happier and more confident when kept among more of their own kind. When there are too few fish in the tank they will be overly shy and will hide even more often than usual.

Do your best to buy enough kuhli loaches so they can be happy. Make sure that you buy a tank that is big enough for the number of fish that you choose as well.

4 – Feed the Loaches Well

Feeding kuhli loaches won’t be hard since they aren’t picky eaters. Even so, you need to feed the loaches well without going overboard.

These fish like to eat sinking nutritional pellets or wafers. This is the type of food you’ll give the fish daily.

Then you supplement that by giving the fish protein-rich foods such as brine shrimp and bloodworms. The fish also like to eat green veggies such as kale and lettuce.

Feed these fish twice per day and give them only as much as they can eat in two minutes each time. This keeps them from overeating.

5 – Hiding Spots Are Necessary

These fish won’t feel comfortable in the tank if they don’t have hiding spots. You must ensure that there are more than enough hiding spots in the tank.

Otherwise, the fish might become stressed and this can cause issues with sickness. They like to hide in little caves as well as driftwood.

It’s wise to put plants in the tank as well. This will ensure that the fish feel comfortable in the tank.

Common plant types such as java ferns, anubias plants, and java moss will work well. Floating plants such as hornwort will be good choices, too.

Final Thoughts

You have a much better idea of how you can keep kuhli loaches alive for a long time now. They can live for ten years or longer in a fish tank.

If you want your fish to have a shot at living for fourteen years it’s important to focus on caring for them well. Give them a tank that’s the right size and make sure that you focus on keeping the water quality high.

Feed the fish very well and be sure not to go overboard when feeding them. Keep the fish in a tank that has plenty of hiding spots, too.

These fish do best in groups of three or more. If you want the fish to be more confident and active in the tank it’s best to go with six kuhli loaches or more.

You’ll have a good time caring for kuhli loaches and you’ll find that they’re very beginner-friendly. It shouldn’t be tough to keep these fish alive for around ten years so long as you’re paying attention to their needs.

Be sure to let others know what you learned about kuhli loaches today. You might be able to help friends or family decide whether kuhli loaches are right for their tanks.
