The Serpae Tetra originates from South America and goes by a variety of names which can cause some confusion. 

It has a distinct red colour to the body  and is tall and compressed.  The shades of red can vary from bright red to reddish brown.

The body is decorated with a black comma-shaped mark that is found right behind the gill cover.  As the Serpae Tetra grows these markings fade and may well grow smaller.

The anal fin is red and fringed with black and white layers the tail and ventral fins are red whilst the dorsal fin is tall and black with a thin white fringe.

Your aquarium needs to be at least twenty four inches long and well planted as the Serpae Tetra likes to stay close to the surface amongst the plants.  Their natural habitat has quite dense plant life and they will appreciate plants that cover the surface of the tank.

Serpae Tetra (Wikipedia)

This is a popular fish in community tanks and needs to be kept in shoals of at least five or six fish.  Although fairly peaceful in nature they do get in a bit of a frenzy at feeding time and could even be considered aggressive when feeding occasionally nipping fins as they compete for food.

In the wild they are omnivorous and live on a varied diet.  You need to try to keep their diet quite varied in the tank including flake food and frozen food.

The Serpae Tetra will breed quite readily in captivity but as with other fish the fry need to be separated from the main tank to avoid being eaten.  If left in the main tank they will hide in amongst weed until large enough to survive but you will have a much reduced survival rate.
