General Information:

A fantastic beginner fish, tolerant of a wide range of water parameters, but favours hard water. The males vary in their appearence dramatically and are available in many differing colours often with oversized caudal fins of startlingly elaborate detail. The females are larger and somewhat more plain. The attractiveness and ease of care of these fish make them excellent fish for those new to the hobby.

Tank Requirements:

Will live happily in most styles of tank, but does best with lush planting and some floating plant cover.

Diet Requirements:

A good base of quality flake supplemented with twice weekly treats of bloodworm, daphnia and brineshrimp will ensure these fish maintain their elaborate colours and active nature.

Compatibility:

Peaceful. Will happily co-exist with similiar sized fish, but fin-nippers should be avoided as the elaborate fins of the males make tempting targets.

Recommendations:

Should be kept in groups of no less than 6 as these are shoaling fish. Females should outnumber males at least 2 to 1.

Common Problems:

This fish is a victim of inbreeding which has led to genetic deformity and the loss of their hardy nature. Current tank-bred stock can be more susceptible to disease and inappropriate environmental conditions. Does not do well in soft acidic water.

Similar Species:

  

Endlers are close relatives to the Fancy Guppy, and significantly hardier as they have not been exposed to successive generations of inbreeding.

Sexing:

Males have the characteristic gonopodium of livebearers. This specially adapted fin replaces the anal fin. Males are usually much more colourful with more elaborate caudal finnage.

Breeding:

Guppies are prolific and will breed readily with little to no input from the hobbyist. Livebearers, they give birth to live, free swimming young. A great beginner fish to get to grips with fry care.
