Water Parameters

Now, let’s talk about the water parameters and tank requirements for Endler’s Livebearers. These beautiful fish have specific needs to thrive in their aquarium. Here are some key considerations:

NameEndler’s Livebearer
Tank Size10 Gallons

pH Level:

Endler’s Livebearers prefer a slightly alkaline to neutral pH level ranging from 6.5 to 8.5. Keeping the pH within this range helps maintain their overall health and well-being.


Endler’s Livebearers thrive in tropical temperatures. Ideally, the water temperature should be maintained between 68°F and 82°F. Use a reliable aquarium heater to achieve and maintain the required temperature to keep them healthy.

Water Hardness

Endler’s Livebearers adapt well to a moderate range of water hardness. Aim for ageneral hardness level between 12 to 30 dGH and a carbonate hardness between 10-30dKH.

Tank Size

Providing enough space for Endler’s Livebearers is important to make them feel comfortable and keep them healthy. Although they are small, a tank with a capacity of at least 10 gallons is recommended. This ensures they have enough swimming space and allows for the addition of compatible tank mates.

What Do Endler’s Livebearers Like In The Wild

In the wild, Endler’s Livebearers can only be found in freshwater environments, particularly in the northern regions of Venezuela such as Buena Vista Lagoons and Laguna De Patos. They feel right at home in places like streams, rivers, and ponds. One thing they absolutely love is abundant vegetation. 

Plants are so important for Endler’s Livebearers for several reasons. First, the dense plants give them plenty of hiding spots. These little swimmers are quite cautious, and having places to retreat to makes them feel secure. 

Plus, it keeps them safe from potential predators, allowing them to relax and explore their surroundings with confidence.

But that’s not all! Plants also play a crucial role in their diet. Endler’s Livebearers are known to be omnivores, which means they enjoy both plant matter and small aquatic organisms. They have plenty of food to eat from the plants around them, and they enjoy grazing on algae.

Endler’s Livebearers need clean and well-oxygenated water to survive. They need oxygen to breathe, just like we do. So it’s important for them to have good water circulation and sufficient oxygen levels in their natural habitat to keep their gills healthy.

It’s worth mentioning that Endler’s Livebearers are quite adaptable. Although they thrive in their natural environment with specific preferences, they can also adjust to a range of water conditions. Their adaptability is one of the reasons why they’re such popular aquarium fish.

How To Setup A Tank For Endler’s Livebearers 

Now, let’s talk about setting up a tank for our Endler’s Livebearers. By following these steps, you’ll create a comfortable and engaging home for your Endler’s Livebearers. Don’t worry, it’s easier than you might think!

Choosing the Right Tank

First, consider the size of the tank you need. A 10-gallon tank is the smallest size recommended, but bigger tanks are always better. Aim for a 20-gallon tank or larger if you want to keep more Endler’s Livebearers, so they’ll have more space to swim and feel secure.

Substrate and Decoration

Pick a suitable substrate for the bottom of the tank, like fine gravel, aquarium soil or sand, to mimic the natural habitat of the Endler’s Livebearers. Adding live plants like Java fern or Amazon sword, rocks, driftwood, and caves not only looks nice but also gives your fish places to hide and explore. 

Just make sure everything is safe for your fish and won’t hurt their delicate fins.

Ensuring Water Quality

Regular water changes are crucial to maintain clean and healthy water conditions for your Endler’s Livebearers. Ideally, a 10-20% water change should be done every week to keep the water fresh and free from harmful substances.

And of course, you should also make sure you’re using a filter to keep the tank water clean and high quality. For a smaller tank I’d recommend a HOB filter, however, you can use a sponge filter too.

Choosing Suitable Tank Mates

When considering tank mates for your Endler’s Livebearers, always choose non-aggressive fish species that share similar water requirements. Avoid fin-nippers or overly aggressive fish that may harass or stress out your Endler’s Livebearers.

Providing Enough Space for Activity

Endler’s Livebearers are active swimmers who love to showcase their energetic nature. So, make sure to leave plenty of open space in the tank to allow them to freely move around and display their lively behavior.


Endler’s Livebearers are omnivores, which means they enjoy both plant-based and protein-rich foods. To keep their bellies satisfied, so to keep them happy offer them a variety of foods. Start with commercial fish flakes or pellets designed for small tropical fish.

These will provide them with a complete meal. But don’t stop there!

You can also supplement their diet with frozen or live foods such as brine shrimp, daphnia, or bloodworms. Such foods are protein-rich treats that provide essential nutrients. Additionally, introduce blanched vegetables like spinach, zucchini, or peas for added nutrition.

As you feed them, remember to give them food in small portions several times a day. This prevents overfeeding and maintains water quality. Fortunately, as you can see, Endler’s livebearers are not picky eaters at all, and as long as you’ve got a high quality fish food at hand, they’ll be happy!

Male Vs Female

Male Endler’s Livebearers have vibrant colors, fancy fins, and energetic nature. Meanwhile, females have a more subtle beauty, with a calm and nurturing attitude. These differences make each gender unique and interesting in their own way.

Physical Appearance

Male Endler’s Livebearers are the ones that grab attention with their vibrant appearance. They have bright colors like red, orange, blue, and black, which make them really stand out. Their fins are beautifully patterned and their tails are eye-catching. 

One way to tell if an Endler’s Livebearer is a male is by looking at their long, rod-like anal fin called the gonopodium, which is used for mating.

However, female Endler’s Livebearers have a more understated beauty. They have silver or gray colors that help them blend in with their surroundings, providing a natural camouflage. You can recognize them by their slightly rounder shape, especially when they are carrying babies.

Size and Shape

When it comes to size and shape, males and females are quite similar. They are usually around 2 inches long, but males might be a bit smaller and slimmer compared to females.


In terms of behavior, the males are more active and showy. They swim around energetically, flaunting their vibrant colors and fins. Sometimes, they can get a little territorial and compete with other males.

On the other hand, female Endler’s Livebearers are calmer. They spend their time searching for food and taking care of themselves. When they’re pregnant, they find safe spots or vegetation to give birth to their babies.
