Opae Ula Shrimp Dying: 11 Common Causes & Easy Fixes

Opae Ula Shrimp Dying: 11 Common Causes & Easy Fixes

These little creatures are fascinating to observe, but unfortunately, many new owners may face the common problem of Opae Ula shrimp dying. 

But fear not, because we’re here to help you troubleshoot and understand the potential reasons for this. 

From overfeeding to contaminated water sources, let’s dive into the world of Opae Ula shrimp and figure out how to keep them happy and healthy!

Why Are My Opae Ula Shrimp Dying? 

Are you scratching your head wondering why your beloved Hawaiian shrimp are belly-up in their tank? 

Opae Ula shrimp dying can be a frustrating and confusing problem for any aquarium owner. There can be plenty of reasons for this unfortunate occurrence, and most of them revolve around proper maintenance. 

Let’s figure out what could be the cause of their health deteriorating and find out how to help them feel better!

opae ula shrimp dying - reasons

1. Shrimp Tank Is Too Small

Small tanks can lead to big problems and that is something that new aquarium hobbyists should be aware of. 

These shrimp are small and the first mistake many new owners make is to put them in nano/pico tanks. 

So, a bare minimum for keeping these shrimp is a one gallon jar that can hold up to 5 Opae Ulas. But, if you plan to breed more of these little guys, then a comfy 5 gallon tank is the way to go, as it can hold up to 200 individuals!

Not only do smaller tanks make it harder for your Opae Ula shrimp to thrive, but they can also make the environment inside the tank more unstable. 

With less water volume, any fluctuations in temperature, pH, or water chemistry can have a bigger impact on your shrimp. This can cause stress and even death, especially if you’re not diligent about water changes and maintenance.

2. Shrimp Tank Is Not Cycled

You know what they say, patience is a shrimp’s best friend! Well, I guess they say that, at least in the aquarium world. 

The fact that they are so small and hardy does not mean that they will survive in an uncycled tank. 

Cycling your tank in just 24 hours may seem like a shortcut, but it’s more like a highway to disaster for your Opae Ula shrimp. 

The truth is, your tank needs time to age and establish a healthy ecosystem before adding them inside. This involves a process called the nitrogen cycle, where beneficial and nitrifying bacteria break down toxic ammonia and nitrite into less harmful nitrate. 

This cycle can take a few weeks to complete, but it’s worth the wait to ensure a stable and safe environment to avoid having your shrimp die all of a sudden! 

3. New Tank, New Problems

When you transfer your Opae Ula shrimp to a new tank, it’s like taking them from their cozy home and tossing them into a new, unfamiliar environment. 

A new tank may also contain different water chemistry, temperature, and other parameters that your shrimp are not used to. 

If not properly acclimated, your shrimp may suffer from osmotic shock, stress, and may even die. 

4. Fluctuating Tank Parameters

Although hardy, Opae Ula shrimp are sensitive to drastic fluctuations of water parameters (temperature, salinity, TDS, pH). 

One important parameter to keep an eye on is the pH level in your tank. These shrimp like their pH levels to be at 8.0 – 8.5

If you notice your pH dropping too low, you may need to add more buffering agents or perform a water change with water that has a higher pH level. On the other hand, if it is too high, you can add some peat moss or try some other ways to help lower pH levels.

5. You’re Using The Wrong Salt

Different types of salt contain different levels of minerals and elements that can affect the water chemistry in your tank and can lead to Opae Ula shrimp dying. 

Sea salt, rock salt, table salt, and aquarium salt will kill these shrimp and will likely pose a threat to your tank snails as well! 

Instead, make sure to use an artificial marine salt that will provide the right balance of minerals and elements that your shrimp need to thrive.

6. Wrong Water Source

Tap water can contain harmful levels of copper, chlorine, and other metals that can harm or even kill your Opae Ula shrimp. But fear not, there is a simple solution to keep your shrimp safe and sound.

By using distilled or RO (reverse osmosis) water, you can remove all of the impurities and contaminants that are unhealthy for your shrimp. 

7. Too Much Waste In The Substrate 

If your Opae Ula shrimp tank smells funky and your shrimp are dying, it could be due to too much waste in the substrate. 

A dirty tank can lead to harmful bacteria growth and toxic levels of ammonia, which can harm or kill your shrimp.

But don’t worry, you can prevent this by doing regular water changes and cleaning the substrate to remove any excess waste.

8. Contaminated Items Inside The Tank

Contaminated tank decoration, tank plants, rocks, and other items can wreak havoc on the Opae Ula shrimp health.

Some owners might even make the mistake of washing new items with regular soap and tap water, which can contain harmful chemicals.

Instead, make sure to clean all tank items with pure, clean RO or distilled water before adding them to the tank.

9. Bad Or Failed Molts

Molting is a natural process where Opae Ula shrimp shed their old exoskeletons to grow bigger and stronger, but if something goes wrong, it can be a real problem. 

Bad or failed molts are often caused by wrong water parameters and it can be a serious issue for these little guys, leading to illness or even death. 

10. Bad/Unhealthy Stock

Buying Opae Ula shrimp from sketchy sellers can lead to some serious consequences. When you introduce shrimp with bad genetics into your tank, chances are that they are not going to last long. 

If breeders/sellers haven’t done their part well, your poor shrimp may suffer from a weakened immune system, making them more vulnerable to infections and illnesses. 

This can lead to your Opae Ula shrimp dying that will leave you feeling bummed for not doing your research properly.

11. Overfeeding Can Be Lethal

Overfeeding can lead to excess food and waste in the tank, causing water quality to deteriorate and harm your Opae Ula shrimp.

To avoid having your shrimp die due to this mistake, use a glass feeding dish to drop in pellets or wafers. After a few hours, simply remove any uneaten bits with ease. No more rotting leftovers fouling up your water!

Final Thoughts

If you are new to keeping this species, and you want to keep them healthy, it’s important to avoid the common mistakes that can lead to Opae Ula shrimp dying. 

From ensuring proper tank size and cycling to using the right salt and water source, every detail counts.

With a little effort, research, and attention, you can create a beautiful and thriving home for your beloved shrimp!
