The Best Aquarium Size for Tetras:

Congo Tetra is a schooling fish by nature, and best kept in groups of six or more. You need a minimum tank size of 110L to keep a small group of Tetras.
You’ll likely need much larger tanks if you’re planning on introducing some tank mates and maybe even more Tetras—usually, the bigger, the better. These fish are active swimmers, so you need to provide plenty of space to prevent overcrowding.

    Light :

    You can choose to use lighting in your aquarium if that’s what you prefer. Tetras spend most of their time in shaded waters in their natural habitat. To imitate that in captivity, dim lighting would be ideal. LED lights will provide the most customization and allow you to adjust the intensity until you reach the sweet spot.
