Glass Bloodfin Tetra Overview, Care, Breeding & More

Are you yearning for a peaceful fish that does not demand high requirements to care for them? If you need a beautiful fish that fits your criteria, the glass bloodfin can be a great choice for you.

The glass bloodfin tetra, or Prionobrama Filigera, is a peaceful and active fish for the aquarium. When you add this to your community tank, you will be glad to see them moving around the space and feeding on the food you give them.

So, what about this fish? What can you find? Here is where my post enters to fill the gaps. Find out more about this fish below.

This rare species is notable for its transparent body and deep red tail and fins. Its adaptability makes it ideal for planted and community aquariums.

While the Glass Bloodfin Tetra usually inhabits the upper and intermediate regions of the water column, they are frequently observed in the middle and lower levels. Therefore, it is always right to decorate your aquascape from the bottom to the top.

It has a distinctive color and appearance that is not included in other tetras.

If properly cared for, adult fish can reach 5.51 cm in length and survive up to ten years. Because these fish are tranquil, the care level required is suitable for a beginner aquarium hobbyist.

But what I like the most about this fantastic fish is the fact that it can be friendly with other species and even invertebrates.

They are easily noticed in the aquarium, making them the focal point of your showcase. They are hardy and adaptable as well. So, when you miss your temperature a bit, they can still tolerate it.

But, of course, you don’t want to miss a lot there. Too many fluctuations can affect their health badly.

Tank Setup

Bloodfin Tetra requires a moderately moving water environment. They require normal to moderate lighting in the aquarium. Most of the time, your glass bloodfin friends can be flexible with the lighting mode so that you can take them anywhere you want.

This fish is ideal for beginning aquarium hobbyists. If you have a nano aquarium, you can still add a group of these fish to it.

They are readily stored at home, school, hobby, or community facilities. It is up to you since you can also tag along with your friends, family members, kids, or other people to care for the fish. It is easy for beginners.

Water with a pH of 6-8 and a hardness of 2-3 dGH is ideal for breeding tetras. Also, keep the temperature between 64 and 82° Fahrenheit.

You may even keep them in non-heated aquariums. However, they are sensitive to fluctuations. If you think that the water is too cold, you will need to add a heater there to keep your fish comfortable.

To accomplish this, they use plants like Java moss to create a hospitable habitat reminiscent of the Latin American river basins.

That’s why you can share care with someone you trust. If they have no idea, you can give them a basic knowledge of the fish and they will quickly learn to do it.

You can easily raise fish in any tank. However, for school sizes of 5–7 tetras and optimal upkeep, the tank should be at least 20 gallons. You might want to expand your tank or get new ones if you plan to add more groups of fish to your aquarium.

Also, choose the one with more space and a swimming area. The Bloodfin Tetra prefers to swim in the tank’s middle and top regions.

They are likely to be active from dawn until afternoon. Even at night, they will still explore the middle and top dwelling areas.

More plants in the bottom strata ensure privacy and better breeding. It is also a great idea to add moss to your aquarium to provide more privacy for them.

These fish in South America are acclimated to warm rivers with leaves falling into the substrate. For the fish, the deep forest provides much-needed darkness. If you want to assure good breeding and living conditions, develop a habitat extremely close to the original.

A Bloodfin tetra swims in the planted fish tank. The vegetation in big tanks can be a great start for them to thrive and survive for a long time.

Although you can add props, I wouldn’t recommend it if you could add more live plants. Rather than using the space available for something unnatural, you can replace it with natural ones.

Not only will these successfully replicate the origin place of bloodfin tetra, but they will also give them the chance to live the life they deserve in captivity.

The best way to make them live longer is to replicate the tank escape as close to the natural environment as possible. The dark sand substrate is a pivotal standard for this. The substrate will make them recall their home.

When it comes to the lighting of the tank, focus on the dim light to create an astonishing environment for your fish.

You can also add floating plants and static ones. In most markets, you can easily find Java moss. That could be the best option.

They will also need a place to hide. Consider purchasing prop hideouts and caves. You can also throw some natural rocks there. When the algae grow, it can make a perfect replication of their original home.

Last but not least, consider setting up slow-moving water to replicate the true habitat of your glass bloodfin pets.

As mentioned, they often explore the mid to top part of the aquarium. It is also possible that they can make the jump if they find slits at the top of your tank. Consider installing a lid on top of your tank to prevent them from jumping.

Glass Bloodfin Tetra Tank Mates

Your bloodfin buddies are peaceful fish. The most ideal tank mates for them are also peaceful species. The other tiny cichlids can be their best tank mates.

If you like crustaceans, you could consider adding adult dwarf shrimp. However, your glass bloodfin could eat the dwarf shrimp. Instead, you could add the larger friendly invertebrates to your tank mates so that your glass bloodfin fish won’t eat them.

Not to mention that your fish needs to stay in groups of at least six to eight specimens. Consider upgrading your tanks if you are planning to add more specimens to the environment.

Food & Diet

They like brine shrimp, cyclops, daphnia, mosquito larvae, and bloodworms in the tank. All of these items are easily found in the nearest marketplace in your location.

However, a diversified diet is best for your fish, so give them dried alternatives like micro pellets and flakes, which they will happily take.

If you want to make your fish’s stomach full, consider giving them pellets and flakes first, followed by protein sources. This will ensure the maximum health and coloration of your fish.

The Bloodfin Tetra likes flake food, but it is best to offer them tubifex worms, silkworms, daphnia, brine shrimp, dried food, or frozen food occasionally to ensure they get enough nutrients. A good mix between them can be a great idea to maintain their health and wellness.

Interchange carnivore food with plant or vegetable foods.

The Bloodfin Tetra is a busy fish that requires a lot of food. The basic guideline is to not feed them more than they can eat in 3 minutes.

The Glass Bloodfin Tetra is a finicky eater but will flourish and remain colorful on a diverse meaty diet. Meaty meals of all kinds will be accepted. There are also a lot of commercial products that can provide great nutrition for your little buddies.

Breeding Guidelines

Males will have more vibrant red in their bottom and tail fin parts. Females have a chubbier body size with subtle red coloration.

It is not difficult to breed bloodfins by yourself. You will need to separate the tanks for this purpose, though. Therefore, the parents can focus on their reproduction without any distractions from their tank mates.

For the breeding mission, you could set the light at a dim level. Add Java moss to the area of spawning.

Cover the tank base with mesh to protect the eggs from adults who want to eat them.

You can either spawn them in groups or pairs. The male and female groups in separate tanks could get better results.

The eggs will hatch in 14 to 36 hours. Yes, it is very quick, right? The babies will be able to swim freely after three or four days.

You may want to separate the males from the eggs since they tend to be tempted to eat their fry.
