Aquarium Setup for Big Tetras
Decorations
When setting up the aquarium for big tetras, the decorations should be carefully chosen. Live plants and rocks can provide hiding spots for the tetras, as well as create a more natural environment. Artificial decorations should be avoided as they can contain material that may be toxic to the fish.
Lighting
Lighting plays an important role in the health of the fish. Proper lighting is necessary for the plants to be able to carry out photosynthesis. The aquarium should be equipped with a light that provides enough brightness to support the growth of the plants.
Filtration
Filtration is essential for the maintenance of water quality. The filter should be powerful enough to turn over the aquarium water several times per hour. It is also important to use a filter that is designed for the specific size of the aquarium.
Heating
