Description


General: The ancestors of cobra guppies originate from northern South American and southern Caribbean. However, they are currently invasive in tropical locations all around the globe. Cobra guppies are highly adaptable, but will be best off in a planted aquarium. There should be more females than males in an aquarium, as males chase after females and sometimes may stress them. Avoid using filters that create strong currents, as guppies will have trouble swimming.

Fecundity: Guppies will reproduce often and will produce around 10-60 fry per spawn, so it is important to have grow-out tanks set up to prevent overcrowding. Adults have the tendency to eat fry, although the survival rate of the fry will be increased if they are housed in a densely planted aquarium.

Water Chemistry: Cobra guppies prefer a water temperature ranging from 64-82F, a KH ranging from 10-30, and a pH ranging from 5.5-8.0.

Diet: Cobra guppies will accept a wide assortment of food, including frozen or live bloodworm and brine shrimp, flake, and even algae wafers.

Dimorphism: Male cobra guppies are generally more colorful, have longer fins and also have a fin used in reproduction called a gonpodium. Female guppies are larger without as much color.

Compatability: Cobra guppies do well in groups with other guppies, and also can be housed with peaceful fish including small tetras such as neons, small rasboras, freshwater shrimp, and corydoras catfish.
