Black Wido fish (Black tetra)

About The Fish 

The black tetra (Gymnocorymbus ternetzi) also known as the black skirt tetra, high-fin black skirt tetra or black widow tetra is a freshwater fish of the characin family (family Characidae) (which includes all tetras, including the piranha), of order Characiformes. It is native to the Paraguay and Guaporé River basins of southern Brazil, Argentina, and Bolivia

Description

the black tetra has a roughly tetragonal body shape and is greyish in colour, fading from light at the nose to near black at the tail. Two prominent black vertical bars appear just posterior of the gills.The fish Growing to about 6 cm (2.5 in) total length

Tanks Size 

Black tetras Tanks should be 15 gallons and planted

Behavior 

It is a schooling fish, and requires at least 6 in a group, but they can also make do with 3-4 tetras per aquarium Although not generally aggressive towards other species, avoid slow moving, long finned fish like male Betta splendens with this fish. Black tetras can be violent amongst themselves, with weaker fishes sometimes chased and nipped by their superiors.

Temperature and PH 

It will live in warm water (78 degrees F or 26 degrees C), but, coming partly from the Paraquay section of the Rio Paraguay south of the tropic of Capricorn, it will also take slightly cooler water than some tropical fish, and is sometimes kept in unheated aquariums in rooms that do not get cold. This fish, like most tetras, needs soft, acid water, pH 6.5-6.8, with plenty of plants, although it is one of the more adaptable tetras, and is suitable for a community aquarium with a neutral pH, and a temperature of about 24 degrees C ( 75 Degrees F)

Diet 

he black tetra is an omnivore and will eat nearly anything it can fit into its mouth, but care must be taken to ensure that all members of the school receive adequate food. If the food is too large, the tetra will lose interest and leave it to sink and decay, so the size of the food particles must be appropriate. It is best to keep a school of 6 black tetras in a medium tank. The Black Tetra will benefit from the occasional feeding with live foods like daphnia and mosquito larvae, and from frozen foods like blood worms.
