The Tetra Penguin fish, also known as the Thayeria Boehlkei or oblique tetras, belong to the Characidae family and come from the South American continent, exactly from Brazil and Peru, where the Amazon and Araguaia rivers have sweet and calm waters with a lot of vegetation that makes them live quietly. These little fish can reach a size of up to 6 centimeters in length, having a very thin and elongated body. They are generally silvery white with a black band that runs through their entire body. These fish are characterized by their way of swimming since they do it in an inclined way.
If you are thinking of have these fish in your aquariumYou should know that they are very social, calm and friendly animals, so they need to live in an aquarium with other species. de peces that share the same characteristics as them. Oblique Tetras do not cause fights or arguments in the pond, so you can have other animals in the aquarium. I recommend that you have at least 6 or 7 specimens so that the animals feel comfortable and comfortable.
Remember that the aquarium must be at least 50 centimeters long, while the temperature must be between 22 and 28 degrees Celsius. The pH of the water should be between 5,8 and 7,5 and the hardness should not exceed 20. Keep in mind that the decoration of the pond, to emulate the natural habitat of these fishIt must have a lot of vegetation, both floating plants that filter the light, as well as algae, in addition the soil must be dark and sandy.
It is very important that, although we have a lot of vegetation in the aquarium, let's leave free spaces so that the animals can swim freely and do not encounter obstacles.
