What Are The Ideal Water Parameters For Ember Tetra?

Ember Tetra is freshwater fish that thrive in cool water, and they require specific water parameters to survive. What are the ideal water parameters for your ember tetra then?

If you want to keep your Ember Tetra for many years, then you will need to maintain the correct pH level, hardness level, water temperature, salinity level, ammonia levels, nitrate levels, and nitrite levels. You should also remove any tannins from the tank so that they don’t affect your Ember Tetra’s health.

Ideal Water Parameters/ Chemistry For Ember Tetra

You should maintain water parameters for the ember tetra because they are freshwater fish, and they need specific water chemistry to survive.

Salinity Levels

If you want your Ember Tetra to live for many years, then you will need to maintain the correct pH level, hardness level, water temperature, salinity levels (SG at 77°F or 25°C), ammonia levels of 0 ppm, nitrate levels less than 20 ppm, and nitrate levels less than 20 ppm.

pH for Ember Tetra Tank

The ideal pH level for Ember Tetra is between 5.5-6.5 GH. It is quite on the neutral side.

Hardness For Ember Tetra Tank

Ideal hardness levels are around 5dGH to 15dGH. Water below this range may cause your fish stress or even death.

Water Temperature For Ember Tetra Tank

Maintaining the temperature around 75°F (23.88ºC) is ideal for your ember tetra. This is because hey come from cool water in their natural habitat. You can maintain the temperature as low as 73°F (23°C) to high as 84°F (29°C).

Ammonia, Nitrites, And Nitrates For Ember Tetra Tank

You should maintain ammonia levels at 0 ppm, nitrites at 0 ppm, and Nitrates below 20ppm.

Tannins For Ember Tetra Tank

You should remove tannins from the tank, as they will affect your Ember Tetra’s health.

If you add tannin to your ember tetra tank, you may cause stress for the fish or even death if not removed from the water.

How Do You Maintain Ideal Water Parameters For Your Ember Tetra?

Maintaining the ideal water parameters for your Ember Tetra begins with performing weekly or bi-weekly partial water changes to keep all chemicals at healthy levels.

Maintain pH Levels For Ember Tetra Tank

You should maintain the correct pH level for your ember tetra. You may need to monitor KH quite often as it tends to change rapidly depending on how much tannin you have in your tank from driftwood.

If you are using tap water, then this will also affect the carbonate system’s ability to balance out properly so consider purchasing RO/DI filtered water instead if possible! Maintaining high oxygen levels by having plenty of air bubbles moving around the surface of the aquarium can help prevent fish stress too.

Maintain Hardness For Ember Tetra Tank

You should maintain hardness levels of around the ideal range for your ember tetra. You can do this by using the water testing kit and changing the water frequently.

Maintain Temperature Levels For Ember Tetra Tank

One way to help keep water temperature more stable is by using an aquarium heater that allows you to set specific temperatures! If possible, use a submersible heater instead of an external one because it will be able to heat up the tank more evenly compared with other types.

Salinity Levels for Ember Tetra Tank

The salinity level of your ember tetra tank depends on what type and how many fish you have in the aquarium as well as their size and age. You can try raising or lowering SG slightly if necessary but don’t change it too much at any one time.

Ammonia, Nitrites, And Nitrates For Ember Tetra Tank

You should maintain low levels of ammonia and nitrites in your ember tetra tank! Ammonium is the first stage before becoming toxic to fish at a higher level.

Nitrate can be kept below 20 ppm or lower which you may need to remove from your water with weekly partial water changes since it tends to accumulate over time due to natural sources such as decaying plant matter and animal waste too.

If necessary, use an aquarium test kit for accurate information on how much ammonia/nitrite/nitrate is in your ember tetra tank so that you know when they need replacing! This will help keep your tank healthier for the fish.

Maintain Oxygen Level Fors Ember Tetra Tank

You should maintain a high level of oxygen in the water. One way to do this is by having plenty of air bubbles moving around the surface of your tank from an aquarium aerator or filter that pushes out lots of tiny bubbles constantly!

Tetra Whisper Air Pump can be the best option for you.

Healthy fish are more active and you’ll be able to see them darting through the water with ease instead of floating at the top which means they aren’t getting enough oxygen into their bloodstream.

Do Ember Tetra Prefer Tannins?

Ember tetras can survive well without tannin levels if you have good filtration. But it may affect health long term so remove any driftwood pieces from a new ember tetra tank setup as soon as possible!

How Often Should You Change Water In Your Ember Tetra Tank?

You should change 20% of your ember tetra’s water weekly or bi-weekly in order to maintain ideal water parameters! If you have an overstocked aquarium, then consider doing it even more frequently by increasing it to around 40%. This is especially important if you are dealing with high levels of ammonia/nitrite/nitrate too!

Is Chlorine Useful For Ember Tetra?

The chlorine found in tap water isn’t really useful at all unless you need to disinfect something like a syringe. It must not be used on another infected fish recently. It can stress out healthy fish and cause them to get ill since it’s toxic for them!

Chlorine isn’t useful for ember tetras since it can kill fish very quickly due to stress or shock. So make sure there aren’t any sources nearby such as tap water containing chlorine, especially when adding new fish to your aquarium.

What Type Of Water Does Ember Tetra Need?

Ember tetras can survive in most types of freshwater as long as you pay attention to water chemistry. Also, make sure that there is no chlorine in the tap water. They prefer harder, neutral pH (ideally around neutral), and stable water conditions so they can feel comfortable.

Ember tetras do best in soft water with a pH of around seven. These fish are even known to have trouble breeding if they’re kept in harder or alkaline water. So be sure that you provide the correct type when setting up their tank too.


Can Ember Tetra Be Kept In Cold Water?

There is no reason why ember tetras can’t live happily in cooler waters. But it may affect long-term health especially if your aquarium isn’t heated properly! You should try and maintain similar temperatures as other tropical fish. They are native to South America instead since this will help keep them happy and healthy overall.

Do Ember Tetra Prefer Dirty Water?

Ember tetras are actually very sensitive to poor water quality and will get ill if they’re exposed to high levels of ammonia/nitrite/nitrate and tannins for too long. If you don’t have a filter or good filtration system, then these fish probably aren’t the best choice for your aquarium!

Can Ember Tetra Survive In Brackish Water?

Ember tetras can survive in brackish water as long as it is not saltwater. They tend to live near freshwater rivers that are slightly salty at times instead. They may do okay if there’s only a small amount of salt present though. So this isn’t something that needs high attention unless you’re keeping them with other species such as betta fish (which prefer pure/saltwater).


Ember tetras are a fun, active species. These fish can add some color and energy to your aquarium if you have the correct setup. Make sure they’re getting enough oxygen by having an airstone or filter pushing out lots of bubbles constantly!

Don’t forget about weekly water changes too in order to maintain healthy levels of ammonia/nitrite/nitrate along with pH, hardness, temperature, salinity (if necessary), etc.

If you don’t know what type of fish tank filtration system is right for your ember tetra tank then consider using one that has bio-media such as foam blocks. These will help keep them happy overall while keeping nitrates from building up over time.
