Black Phantom Tetra Background Details

Black phantom tetra care routineBefore we get to discussing the care routine of Black Phantom Tetras, let’s quickly run through the species’ background. It always pays off to understand a species’ natural habitat — especially when you’re trying to make it feel at home in your aquarium.

– Native Territory

The Black Phantom Fish frequents the waters of the Paraguay basin and the Madeira basin, in South America. This Characin species enjoys a wide range of distribution, and they’re plentiful in numbers.

Budding fishkeepers will also be pleased to learn that Phantom Tetras are readily available in most aquariums and are generally inexpensive additions to their home tanks.

The species are typically found in backwaters or tributaries, and they’re also known to inhabit lakes and ponds. But, no matter where you find these small Tetras, they’re almost always around patches of vegetation and tree roots.

– Appearance

Members of the Tetra family generally have a trademark look that includes compressed-looking bodies with a spindle-like shape and well-developed fins. Most Tetras will have a forked caudal fin, a sizeable dorsal fin, and a long-ish anal fin. Phantom Tetras do have some of the above described physical attributes.

For example, the bodies of Black Phantoms are narrow toward the heads and tails and give off an oval shape. Their tails are forked, much like other Tetra species. The species also sport a dark spot near their gills.

The fins of Black Phantoms are an exciting feature of the species. For instance, the anal fin is well-defined and connected to their bodies near the tail area. Both the dorsal and anal fins include rays and add to their species’ overall appeal.

You’ll also notice there’s plenty of sexual dimorphism among Black Phantoms. The male Black Phantom Tetra isn’t as colorful as its female counterpart. Additionally, females of the species have a reddish tinge on their caudal, anal, and pelvic fins. Female Black Phantoms have smaller fins overall, and their dorsal fins are typically more vividly black than those of the male Phantom Tetras.

– Temperament

Phantom Tetras are a shoaling species that tend to stick together. Considering their small size, it’s not a bad idea to keep a group of Black Phantoms in a tank because that way you’ll be able to observe them better. Overall, Black Phantom Tetras are peaceful and non-aggressive.

However, the males of the species can exhibit territorial aggression at times because the species does develop an internal hierarchy. Any time a male is challenged by another fish trying to enter the male’s territory you might see some disagreements develop. But, before you have visions of blood and gore, you should know that Black Phantoms aren’t very visceral fighters.

Instead, the males partake in what you call a parody of a fight where they’ll mirror each other’s moves and swim around each other in circles. Thankfully, you can only expect an interesting display of theatrics and no actual damage in Black Phantom “fights.”

Once the males have shown off their abilities and dealt with the encroachment of territory in their own fishy way, things will settle down and go back to normal.

Black Phantom Tetra Care and Maintenance

Novice or beginner fishkeepers can be excused for thinking the upkeep of fish in captivity is easy-peasy. For the most part, care of Black Phantoms doesn’t require too much effort, but that doesn’t mean you’re going to get off scot-free. Here are the tank care specifics of the species that interested aquarists should know about.

– Tank Size

As a shoaling species, Black Phantoms do well in groups, and that’s one reason they require a roomy aquarium to move around in without feeling overcrowded.

Most people look at the Black Phantom Tetra size and think the species could adjust in a small-sized tank. But that’s not the case. Not only do Phantom Tetras require plenty of space (they’re pretty active), but small tanks are also harder to maintain in terms of water conditions. So, in the case of tank size for Black Phantoms, the adage — bigger is better — is undoubtedly true.

This species’ minimum tank size requirement is 20 gallons, and a tank measuring at least 24 inches is highly recommended. However, be advised that these numbers are suitable for a group of Phantom Tetras that contains six fish. If you want to add more Tetras, you’ll definitely be needing a bigger tank.

Phantom Tetras also require the presence of aquatic plants — which means starting off with a sufficiently big tank will pay off in the long run. It’s also important to note that overcrowding the species will lead to frequent mock fights between the males. While these fights usually don’t cause injuries, they can affect the species’ stress levels, directly impacting their health.

– Water Conditions

Black Phantoms are hardy by nature, but they’re sensitive to fluctuations in water conditions. One sure-shot sign of sub-par water conditions is the species gradually losing color. Here are the water parameters you’ll need to follow to avoid such an occurrence.

If you’ve always wondered why fish tanks need to be monitored and controlled regarding water temperature, it’s because fish can’t maintain their body temperatures. When the temperature of the water fluctuates, so does a fish’s body temperature. A sudden acceleration or drop in temperature will affect your Black Phantom’s health. Because the species inhabit moderate waters in the wild, they need temperature ranges of 72 to 82 degrees F in captivity.

If you live in a region that experiences lower temperatures, it’s best to invest in a water heater. It’s also wise for aquarists to have a water thermometer handy to measure the water changes. Black Phantom Tetras require a tank’s pH and water hardness levels to stay between 6.0 to 7.5 and 8 to 18dGH, respectively. However, sticking to 10dGH is best.

You can maintain the water conditions to keep your Black Phantoms healthy by changing 10 percent of the tank’s water daily. If that’s too taxing, you can always opt for a 50 percent weekly water change. Fishkeepers will also need to invest in water-testing kits and a top-quality water filtration system. Filters will help eliminate waste and keep the tank’s nitrogen cycle stable.

– Habitat Requirements

Black phantom tetrasHabitat-wise, Black Phantoms don’t require too much work. Being freshwater fish that are used to underwater vegetation, Phantom Tetras thrive in aquariums with live plants. Additionally, the presence of aquatic plants can also help boost your tank’s closed ecosystem, making it safer for your fish to live in.

Ensure you add plants to the sides and back of your tank — giving the Phantom Tetras plenty of room to move around. You can opt for floating plants or fine-leaved species, depending on your preference. Aside from the foliage, fishkeepers also need to provide the species with a mixture of sand and gravel substrate to mimic a river’s bedrock.

Aquarists who plan on breeding the species once they reach sexual maturity should know that Black Phantoms are an egg-scattering species, so the presence of plants in the breeding tank is a must.

You also can add driftwood or rock decorations to give the fish tank a natural look. Another pro-tip is to add dried leaves to stain the water. However, don’t forget to fish out the dried leaves before they start rotting.

– Diet

Black Phantoms are omnivores and particularly easy to feed — which is good news for fellow hobbyists.

The species’ diet in the wild includes items like small insects, crustaceans, and tiny water organisms. That means, in captivity, you have the option of feeding Black Phantom Tetras a diet that consists of food-quality flakes and live or frozen food (like brine shrimps or bloodworms).

Black Phantoms require feeding no more than twice daily. Only give the species enough food they can consume within 2 to 4 minutes. Once the fish are done feeding, scoop out the leftovers to avoid water pollution.

– Lifespan, Size, and Growth Rate

Aquarists will be happy to learn that Black Phantom Tetra lifespan ranges between four to six years. In the wild, the species are known to live up to eight years; but anything beyond six years is a rarity in captivity. The short-to-medium lifespan is one reason why experts recommend housing this species in a group. Seeing fellow fish helps Phantom Tetras adjust better and can keep them from getting scared easily.

Adult Black Phantoms can reach 1.4 to 1.8 inches upon full maturity. In short, these fish won’t grow much longer than the first two joints of your index finger. The species isn’t particularly fast-growing, and take their time reaching their maximum size potential.

You’re probably wondering how visible Black Phantom Tetras are in the water. However, this is not something you should be overly concerned about. The species’ luminous silver-grey color and black spot (around the gills) make them pretty to observe.

– Health Considerations

Black Phantom Tetra are vulnerable to all health issues that freshwater fish face. These conditions include stress, bacterial and viral infections, Ich, parasites, flukes, etc. However, the good news is you can avoid all these problems by staying on top of your water parameters game. It’s essential to stick to daily 10 percent water changes (or 50 percent weekly water changes). Doing so will help eliminate any parasites lingering in the water that can cause trouble.

Aside from that, a robust water filtration system and maintaining water temperatures will help keep your fish safe from stress and other diseases. Aquarists should never add a new group of Black Phantoms to an existing tank without following proper quarantine techniques.

If you suspect your fish are coming down with something (if they appear lethargic, pale, or aren’t feeding), a quick trip to an aquatic veterinarian is the correct course for diagnosis and proper treatment.

Breeding Black Phantoms

Black Phantoms are an egg-scattering species, and they’re quite easily bred in captivity. Aquarists looking to increase the Black Phantom numbers will require a separate breeding tank. Setup of the breeding tank will require a water heater, filter, aquatic plants and breeding grass. Lighting in the breeding tank needs to be dim.

Black Phantoms breed in somewhat acidic waters, so you’ll need to have the pH levels stable at 5.5. Water temperature should be about 77 degrees F. Once the breeding tank is set, shift the male and female pairs to the breeding tank and feed them a live food diet.

If all goes well, the pair(s) will spawn, and you’ll be able to observe the eggs by the next day. To ensure maximum fry survival, shift the adults back to their original tank. The eggs will be ready to hatch within a few days. Once the eggs hatch, you can feed them infusoria until they’re old enough to feed on microworms.

Tank Mates for Black Phantom Tetras

Black Phantom Tetras can adjust in single-species and community tanks. However, it’s best to introduce the species in a group and stick to tank mates that aren’t aggressive. Tetras that are similar to Black Phantom size make good companions for this species.

Try to avoid pairing Phantom Tetras with other similar-sized species that are slow-swimmers, because the Black Phantoms may overeat others’ food shares and cause them to starve.

Suitable tank mates for Black Phantom Tetras include Gouramis, Cichlids (small), Tetras (similar-sized) and Rasboras.
