Having learned why tetra fish are preferred, let’s look at the most popular tetra fish species you are likely to encounter.

How to Set Up a Tetra Fish Tank
However, as much as their types, you need to determine what your tetra fish needs regarding the environment. Basic instructions on putting up the tetra fish aquarium are provided to ensure that the fish are always healthy.
1. Tank Size
Even though Tetra fish varieties are relatively small, they require a proper swimming space. The general idea is that most breeds of tetra fish require a 10-gallon tank as a base, but the larger the tank, the better, especially if you intend to have a group of fish.
2. Water Conditions
- Temperature: 72°F – 82°F
- pH: 6.0 – 7.5
- Water Hardness: Soft to moderate
Filtration: Water quality depends on the type of filter used. A good filter is very important.
3. Planting
Tetra fish enjoy planted tanks. Plants offer the fish some shelter and make them feel more at ease. Living plants like Java ferns, Amazon swords, and moss are handy.
4. Lighting
Tetras are sensitive fish and, therefore, require low light since this is what is obtained in their habitat. Too much exposure to light is not good for fish, so you should use moderate lighting when planting tetra fish aquariums.
Common Mistakes to Avoid When Keeping Tetra Fish
As previously mentioned, tetrafish are relatively low maintenance, but some things should never be done to prevent harm.
- Overcrowding the Tank: Amateurs are always warned of the common error of overcrowding the tetra fish aquarium. Tetras require most of their aquarium space to swim and be active. Stick to the rule of one fish per inch of water or at least one inch of fish per gallon of water.
- Inconsistent Water Conditions: Tetras also react to changes in water. Rapid changes in temperature, pH, or hardness affect the fish and may lead to disease. Water quality testing is another important frequency that is needed.
- Ignoring Schooling Needs: All tetra fish types are generally schooling fish. They appear more secure, and are not as stressed when housed in groups of not less than six. Do not keep a single tetra fish because the fish will get stressed and lonely.
Final Thoughts
As mentioned, there are so many tetra fish available in the market, and every tetra fish lover should find an appropriate species to have. They range from the easiest neon Tetra to the dazzling Cardinals and Serpae Tetras, making it easier for one to find a species suited for the tank. Do not forget that being cold-water fish, tetras are perfectly adapted for the aquascape with stable and clean water in the tank.
For any beginner starting a tetra fish aquarium or even adding to his collection, following the above guide will enable him to set up a bright, healthy, beautiful, and ocular tetra fish aquarium.
