Here are the top 10 best aquarium plants that you can use in your tetra aquarium.

In the wild, they live in the flowing water of big rivers, but sometimes they swim in the tributaries in the search for food and thick plants. They are schooling fish, who feed on insects.

Colors, Size, and Markings

As I mentioned prior, Balloon Red-Eyed Tetras are relatively large. The maximum size of Balloon Red-Eyed Tetras is 3 inches.

Besides, these tetras have a distinguished color pattern of black and silver that is accented with an eye-catching red marking above their eyes. So, they create an impressive display and add dynamic energy to your tank, when kept in school.

Ease of Care

Balloon Red-Eyed Tetras are social creatures, who are very easy to care for. They are not demanding fish, so good for beginners.

As in the wild, there is no much light due to lots of greenery. So, it is better if you keep soft lighting in the tank which you can do by adding some fluctuant in the water like rocks, driftwoods, and plants. Also, you can create a natural habitat by providing them some hiding places.

Furthermore, the fish can jump, so you must keep them in a closed tank (more than 40 cm long), along with some areas shaded by the plant.

Balloon Red-Eyed Tetras do not like strong water flow, so you must keep the filter that does not create one.  Also, every week, you much renew 20 to 25% of the water.

However, Balloon Red-Eyed Tetras have a great natural tolerance to a wide range of water parameters. Their characteristics make them well suited for a variety of aquarium setups including a community aquarium.

Balloon Red-Eyed Tetra Diet

The natural diet of Balloon Red-Eyed Tetras consists of small insects and planktonic animals as well. However, in your home aquarium, you can feed frozen or freeze-dried brine shrimp, daphnia, bloodworms, and tubifex.  You can also treat them with micro pellet food and high-quality flake food.

The following items are the best for your balloon red-eyed tetra diet:

Compatibility

As Balloon Red-Eyed Tetras are peaceful creatures, they are compatible with other peaceful fish. But, being very active, they can also scare and disturb other calm fish. So, keep them with the fish who are as active as them. E.g. Black Skirt Tetra, Emperor Tetra, Cardinal Tetra, and so on.

Also, they nip at the fins of slow-moving and long-finned fish. So, do not keep them with fish with large fins. E.g. Angelfish.

Additionally, other tetras may pick on them at times, so you must keep an eye on the community.

Sex Differences

The difference between male and female Balloon Red Eyed Tetra is that male Balloon Red Eyed Tetra tends to be smaller and thinner than female Balloon Red Eyed Tetra.

Breeding the Balloon Red-Eyed Tetra

Balloon Red-Eyed Tetras become reproductive when they are 10 months old.

When you are attempting to breed Balloon Red-Eyed Tetras, set up a separate breeding tank. The tank water must be warmer (24 to 28 C), acidic (pH 6 to 8), and very soft.

Moreover, the tank must be dimly lit with clumps of spawning mops or java mops. A layer of the mesh also works fine if the space is wide enough for the eggs to pass through and, small enough for keeping the parents out. You can add a small air-powered sponge filter which will also provide gentle water flow.

You can use the following items:

Before Spawning

Before spawning, you must prepare the fish: keep them in a separate tank, add plant food into their diet, and feed them well for about 7 to 10 days. The fish that I kept in the breeding tank in the evening will start their breeding game in the morning.

Furthermore, the female lays up to 1000 eggs that lay on the tank bottom, or even get stuck in the plant leaves.

After Spawning

Once, the spawning has occurred, remove the mating pairs. If not removed, they can consume both eggs and hatching fries. The egg will hatch in one to two days after the pairs lay them.

Additionally, after 5 to 6 days, feed fries some fry foods like freshly hatched brine shrimp or finely crushed flake foods. Sometimes, you may find that the eggs are not hatching. Even then, you do not worry, the eggs can be unfertilized. Unfertilized eggs do not hatch.

Besides, when the babies become a few months old, you can introduce them to the adult tetras.

Nevertheless, you can spawn Balloon Red-Eyed Tetras in pairs, but for the best result, you can spawn them in a group of 12 individuals, with half of the males and half of the females.
