My Three Endlers


Endler's Livebearers

Endlers are extremely active fish and are tons of fun to watch. They were first discovered by Franklyn F. Bond but went unnoticed for 40 years until they were rediscovered by professor John Endler, hence the name "Endler's Livebearers". Now they are popular pets and are sold in pet stores in many places in the world. However, their natural breed in the wild is severely endangered or completely extinct altogether. That is why we must care for our endlers right, so I wrote this post to help you out, read on to find out how to care for them and more!


First off, let's discuss classes. There are three classes: N class, P class, and K class.

N Class: N class are any endlers that have come from their natural habitat in the waters of Venezuela, you must have records kept that they are from Venezuela or they are not considered true N class endlers.

P Class: P class endlers are endlers that are still true endlers, however, they did not come from their natural habitat. This type of class includes black bar endlers, peacock endlers, and more. N class includes the same types, however, they are from their natural habitat in Venezuela.

K Class: K class is any endler that has been crossbred with any other livebearer such as guppies. This includes Japan Blue endlers, Scarlet Red endlers, any Snakeskin endlers, Tiger endlers, and more.

Tank Conditions

Endlers are tiny fish and are only about 1 inch for a male and about 1.8 inches for a female, however they are social fish so they should be kept in minimally groups of 3. The minimum tank size for three males would be a 5 gallon, if keeping any females or a greater number of males, 10 gallons would be the minimum recommended size. But, as with most fish, the bigger the tank, the better. Ideally, you'll want a temperature that does not fluctuate and is set to about 72 to 78 degrees Fahrenheit. The pH levels should ideally be 6.7 to 8.5. Hardness should not be a problem up to 25dGH. Your tank should have a lot of plants and decorations for hiding spaces but remember, don't overload the tank with decor that there is not enough space to swim, because endlers are highly active and energetic. Endlers also enjoy floating plants, so its good to add some of those to your tank, especially if you plan to breed.


When buying food it is always important to remember that endlers are very small fish which means they require small food. They are omnivorous and can eat micro pellets and tiny fish flakes; small algae wafers; and bug bites. Live and frozen foods, such as brine shrimp, daphnia, and bloodworms would be a great treat to incorporate into their weekly diet. If they are not eating, try taking a tiny bit of tank water or dechlorinated tap water and put it in a small container. Put a small pinch of pure garlic powder in, then let the food soak inside for about 5 minutes. Then give some food to your fish, this should help entice them to eat. If they begin to accept food with garlic, begin adding less and less garlic powder each time until there is none left and your endlers will just eat the regular food.

Additional Info

Some other things to keep in mind:
  • Limit your lighting schedule. Leaving bright lights on in the tank for over 12 hours can make the endler's colours fade.
  • If you get both males and females, the ratio of male to female is minimally 1:2. You could also do all males or all females.
  • No K class endler breeds are in N class because guppies and endlers live in different places. To tell if your endler is male or or female is quite easy, males have vibrant colours and females have only grey or silver on their body. They can still have colours on their tails.
  • Endlers are a livebearing fish. When females are kept with males, expect to see large numbers of live fry on a monthly basis.

Endlers are a great fish with high energy levels and lots of personality. I hope you have lots of fun with your fish and that this guide will help you along the way!

This has lots of good info, it will be very helpful since I will be getting some Enders soon.
I love that there's an article about endlers. But the remark that guppies and endlers live in other areas is not correct. Wether it concerns the endlers coming from the Cumana or Campoma region, also guppy populations are present. Even in a number of natural waters, both species live in one and the same waters. This makes it also possible that natural hybrids can occur. Some of the known wild endler strains are subject to this issue.
Also can one keep a male/female ratio of 1m:1f without any problems. Wild endlers behave different than fancy guppies when it comes to chasing the females. The harassment is low with real endlers in comparison to guppies.
great job! Never knew about the classes!
This is a great article! Includes all helpful information for people attempting to keep them. All of this information has been correct and helpful.
Excellent information as I'm looking into buying endlers for my 15gal. Thank you!
I loved your article, especially the classes of endlers, which I don't always remember! I was wondering if you may be able to add pictures of more of the different types of endlers and if you might be able to list more as well?
