Lighting

Soil

Small pebbles or sand can be placed on the aquarium’s bottom because tetras do not disturb the substrate. There are no particular requirements for the soil.

Decorations

Many shelters are required for a school to live comfortably, including:

• decorative grottoes;

• amphoras;
• snags.

Plants

Tetras enjoy hiding among the stems of algae, but it’s important to remember their small size and avoid packing too many plants in one area. Thick underbrush can make it difficult to see, and the fish will blend in with the background.

Feeding

Although their food is not particularly fancy, it is important to take into account that tetra has a unique diet because they only consume the water’s surface. Anything that hits the bottom is going to stay there. Live food should never be used for feeding because it can contaminate water.

You can use any other professional food in addition to the specialized foods "Tetra Mix" and "Tetra Rubin."

Compatibility with other fish

It is best to avoid settling copper tetras with fish that have veil plumage, like veiltails.
