Water Conditions

These fish will flourish if kept in the correct water conditions, If the ideal water conditions are not met for this fish they could suffer and will develop issues such as disease, growth issues and many more issues.

These fish are active swimmers and like a tank with lots of swimming area.  They also like to have floating plants to hide in.


Ideally, Endler livebearer will need to be kept at a temperature between 75-81°F.  They will survive in water temperature between 64-75°F but they will not thrive.

It is recommended to use an aquarium heater to keep the water temperature at the recommended setting.  If you are after a heater check out the ones available on amazon

If the water temperature is outside the ideal conditions the fish will not thrive and will most likely develop the following conditions

I recommend that you monitor your aquariums water temperature by using an aquarium digital thermometer.  Check out these ones from amazon

The ideal PH Level for Endler livebearer is between 6.5 – 8.5, They will require low to moderate water hardness.

You can monitor your aquariums water using a PH water tester kit available on amazon

Oxygen level

As with most fish it is important for these fish to live in well oxygenated water, For this I recommend to install an air pump in to your aquarium as this will insure that the water is well oxygenated. You can pickup an air pump online from amazon.

Tank Setup

There are certain things we need to consider when we are selecting a tank, we know the needs of this fish are

Tank Size

The main thing you need to consider when selecting a tank is if your fish will breed?  Endlers are prolific breeders so you will need to accommodate this if there is a chance of them breeding.  If you don’t plan to breed them you can keep them in a minimium of a 5 gallon tank.

How many endler’s to keep in a 5 gallon tank? You can keep 6-8 Endler livebearer fish in a 5 gallon tank, If they start to breed it is recommended to keep them in a 20 gallon tank.

Can Endlers live alone? Yes but it is not recommended to keep them alone.  They will often become a little bit more aggressive and chase away other fish that come near them

These fish love a tank that has a lot of plants, especially floating plants.  I would recommend the following plants

  • Java Moss
  • Duckweed
  • Water Sprite
  • Java Fern


How often do Endler livebearer fish need to be fed? You should feed them two times a day with 2-4 pinches of food. It is not recommended to feed them a larger quantity in one sitting as they will not eat all the food and this will deteriorate the water quality over time.

What should I feed my Endler livebearer? You should feed Endler livebearer fish flakes as this will provide a good balanced diet for them. If you want to give them a treat you can feed them blood worms, frozen or live shrimp and tubifex.

In the wild they eat small insects and algae.  If possible it is a good idea to replicate this in your home aquarium to.

When the males are ready to breed they will spread their fins and will chase the female fish and also chase off other males.

How to tell if Endler livebearer is pregnant? The easiest way to see if a female Endler livebearer is pregnant is to look at her gravid spot, If it is dark and large then she is pregnant.

These fish are prolific breeders because they can store sperm from males for up to nine months in which they can use to produce fry.

Can Endlers mate with guppies? Yes they can, they will produce fry that will contain characteristics from both the endler and guppy fish. They will breed with all types of guppies.


The last thing I want to go through is the common diseases these fish could suffer from.


Ich stands for Ichthyophthirius multifiliis which are small parasites that attach to the outside of the fish.  They will look like small grains of salt.  If your fish are suffering from Ich you can do the following to help them

  • Turn the heating up to 84°F
  • Apply Ich X to the water (Available from amazon)
