Plants with roots are usually planted in the ground, floating leave on the surface of the water. Often, they prefer Javanese moss, echinodorus, Thai fern.
  3. The water temperature should average +25°Celsius. Fish can tolerate a slight decrease. Acidity should be in the range of 6.5–7, stiffness on average 4–8.
  4. Lighting is selected with medium intensity.
  5. One should use dark-colored soils, gravel, and sand. Besides, you can decorate the aquarium with snags, and they also serve as a shelter for the fish. Other Water inhabitants will also be able to relax behind them.

  1. The size should be suitable.
  2. Nutrition must be balanced. Feed usually alternate days. The condition of aquarium pets directly depends on this.
  3. In nature, These tetras feed on small aquatic animals, insects from the surface. In captivity, you can use both live food (crustaceans, bloodworms, small insects) and dry (special flakes, granules). Vegetable nutrition is also suitable (dandelions, spinach).

Serpae Tetra Breeding

Breeding must begin with the preparation of the spawning tank with a capacity of not more than twenty liters. A separator grid is placed at the bottom – it will protect future eggs from parents, who can eat them.

Use dim lights in the aquarium, and the soil isn’t necessary, but plants need to be used, especially small-leaved, long-stalked varieties. You can take a small bush of Javanese moss or fern.

For the breeding of Serpae Tetras, Water must meet the following requirements:

  • the temperature within 25-28 degrees;
  • acidity – up to 7;
  • stiffness – not more than 15.

For this, a concentrated decoction of peat is poured into distilled water, left to infuse for one or two weeks.

For breeding, a couple of fish or even a small group are selected. A week before the expected event, separate sex maintenance and abundant feeding should be practiced. In the evening, the fish are placed in a spawning ground.

Spawning can occur in the morning or in a few days. Then the fish are precipitated, and a container with caviar is provided with weak aeration. In addition, it must be darkened.

If spawning does not occur within five days, then this entire period of fish is not well fed. If nothing happened, then the serpae tetras should be placed back into the aquarium and try to repeat the procedure after a couple of weeks or a month.

Offspring Care

Usually, you get two to three hundred eggs, which sink to the bottom, sticking to the foliage. Caviar should not be touched as it is sensitive. The fry will hatch after a day or two. They will stick to nearby plants or glass containers. They begin to swim after 4-5 days.

When the fry begins to swim you can start feeding them. For this, use ciliates, nauplii of cyclops, rotifers, small nematodes. Every two weeks, the water in the tank is changed, gradually increasing hardness. Further care for the fry is no different from the content of adult individuals.

The growth of fry occurs rather quickly. After 8-10 months, they are ready for breeding. And if this is required to be done, then it is enough to repeat the simple procedure of breeding the fish only.

It’s quite simple to take care of and breed serpae tetras. It is only necessary not to forget about the individual characteristics of this type of fish and support for the purity of water in the aquarium.

If you approach the matter responsibly, then these small creatures will delight their owner with their bright appearance, activity, and fertility.
