  • Adult endlers should be fed small amounts once or twice a day.
  • Baby endlers should be fed 3-4 times a day.
  • Avoid overfeeding, it could lead to obesity.
  • Separate sick tank mates to hospital tanks or a seperate tanks until they recover to avoid the community spread of disease.
  • Check if all the tank accessories are in working condition or not.
  • Use gravel siphons to remove leftovers from the substrate on a daily basis without fail.

Bi-weekly care tips  for endler fish

  • 25-30% water should be changed weekly once.
  • Sudden water changes can affect male endlers’ fins.
  • You can use a water test kit to know when to change the water.

Why is endler fish care important?

Endlers are perfect cold water fish for home aquariums.They are playful,active and inquisitive fish.It is very important to give proper care to endlers because they are sensitive to temperature and pH fluctuations.

They have a very short lifespan, and are not easily available in pet shops.The most important thing is they are at the verge of extinction. So,if you are not maintaining them properly or not providing them proper care they may die off pretty soon.

How many endler fish should you start with as a newcomer?

Starting with a healthy fish is key to keeping your endlers healthy, so make sure to avoid endlers with lesions, abnormal growth, white spots or any other physical abnormalities to ensure that you are having a healthy endler.

These are schooling fish so you can start with 2-3 fish couples, as they are very active.

Habitat of endler fish

Endlers are native to campoma and kumana regions of Venezuela. They are found in shallow water near to shore,where the water current is slow.The wild population is under threat due to their habitat destruction.

Types of endler fish

Endlers used to come in black silver variety with little dots of color on it but are now modified into 4 billion hybrid versions.

Endlers classification on the basis of their genetic purity:

  • n-class endler(orchid endlers) come from Venezuela (purest genetic form)
  • p-class endler,pure form but the genetic origin is unknown.
  • K-class(tiger yellow and paradise endlers)Hybrids/crossbreeds forms 

Different strains or colors of endler fish

List of endlers color types:

  • Sunburst cobra
  • Red stripe
  • Yellow tiger
  • Snake chest

  • Endler males are more colorful (fluorescent color) than females (silver or greyesh)
  • Males are recognised by stick like appandage near their anal fin, gonopodium (anal fin modification for mating)
  • Females can hold sperms for a month or so.

Endler fish lifespan

Average lifespan of endler fish is 2-3 years.Their genetic purity and the amount and type of care they are getting will decide their lifespan.

Females live shorter than males,due to frequent breeding.

Tank size for endlers

  • Endlers are tiny fish and dwell well in a nano aquascape.
  • Endlers thrive well in community tanks.
  • Size of the tanks should be about 8.8 gallons (40 liters)
  • A 10 gallons tank can accommodate 2 females and 1 male endler and a 20 gallons tank can accommodate 9 endlers.
  • Endlers are fast swimmers and are mainly found in the upper and middle region of the tank.
  • Endlers are jumpers so provide a lid to your aquarium.They usually jump out of the aquarium when they are stressed and frightened.

Light intensity for endlers

Endlers need standard aquarium lights in their tanks.It is better to install a light timer in their tanks to regulate light and darks hours to maintain their circadian rhythm.Keep them away from direct sunlight and too much bright lights too.

Substrate for endlers

  • Endlers are not so particular about their substrates.
  • A soft sand substrate is preferred if you are interested in keeping a substrate in their tank.
  • Substrates could be dark or light.
  • A rough substrate may damage their avoid using rough substrate in their tanks.

Water parameters for endlers

  • Endlers prefer hard water in their tank.
  • They don’t like high water currents.So keep the currents of water slow (lentic water), because fast currents might stress them.
  • They are very very hardy fish and can live in almost any pH and water hardness.
  • Optimum pH – 6.7-8.5 (neutral pH is best)- crushed corals and wonder shells can be used to maintain the tank pH.
  • Water hardness- 9-25 dGH
  • They prefer adequate filtration,sponge filters can be used.
  • You can also use a hang-on back and canister filter to remove biological waste from their tanks.

Temperature for endlers

  • Endler fish prefer warmer temperatures in their aquarium.
  • Warmer water is necessary for their rapid growth.
  • Optimum temperature – 64 F-84F (anything between this range is suitable for them to thrive in aquarium settings.
  • They don’t need a heater if the temperature in your home is reasonable.
  • Maintain a proper temperature for their metabolism.
  • If the required temperature is not maintained then they might get stress and infectious disease.

Tank plants for endlers

  • Tank plants provides good hiding space for endlers
  • Thick plant with dense vegetation is important
  • Floating plants with small leaves
  • Live plants (hornworts and guppy grass,dwarf hygro)
  • Artificial or fake plants
  • Along with plants,you can add algae in their tank.
  • Stemmed plants

Tank mates for endlers

Compatible tank mates:

  • Swordtail
  • Platies
  • Panda cory (bottom-dweller)
  • Kuhli loach
  • Harlequin rasbora
  • Celestial pearl danio

Tank mates to avoid:

  • African and South American cichlids.
  • Common guppy (interbreed)
  • Common plecos
  • Mollies (interbreed) 
  • Crayfish
  • Turtles
