In this article, we will answer some commonly-asked questions about whether these two types of aquarium fishes can live together peacefully in a tank.

Brief Details About Black Skirt Tetra And Guppies

They are also known as “million fish” because of their population explosion in the wild due to human intervention.

Tank Size For Black Skirt Tetras And Guppies

Guppy fish is a little bit bigger and can grow up to four inches long, so you should have at least 20 gallons of water per one guppy. In addition to that, black skirt tetras are better off in larger shoals rather than smaller ones because they enjoy being with their own species more than anything else.

Water Parameters

Black skirt tetra will thrive best in moderately soft water (or high water hardness).

Water temperature: 60°F-80°F

pH level 6.8 – 7.0

Water hardness (kH) level 4.0 – 8.0

On the other hand, guppies love open spaces as well as warm temperatures ranging from 74°F-82°F and moderately hard water (or moderate/high dGH). Keeping these parameters straight for both fishes’ tanks can be a bit of a headache, so we recommend checking out this awesome chart – it will make your life much easier!
