History and First Sighting

The Scarlet Badis (Dario dario) was first identified in the clear waters of India. Initially recorded in the early 20th century, its unique vibrant hues immediately captivated ichthyologists. Nestled within India’s freshwater streams and rivers, these diminutive fish have since become a favourite in the aquarium trade.

Their discovery offered enthusiasts a glimpse into India’s rich aquatic biodiversity, underlining the importance of conservation efforts for such remarkable species.

Classification and Distribution

The Scarlet Badis, scientifically termed as Dario dario, belongs to the Cyprinidae family, which is an extensive group including many freshwater species. This classification underscores its relation to some common carp and minnow species.

As for its distribution, the Scarlet Badis is predominantly found in India, particularly in the regions of West Bengal and Assam. These fish favour slow-moving or still waters of streams, rivers, and ponds. The specific locales they inhabit emphasise India’s role as a hotspot for diverse and unique aquatic life.

Scarlet Badis Appearance

Size and lifespan

The Scarlet Badis is a testament to the adage that good things come in small packages. Measuring in at a diminutive 2.5cm at full maturity, this fish is one of the tiniest additions one can have in an aquarium. Despite their small stature, they command attention with their vivid colouration.

In terms of lifespan, with optimal care and a well-maintained habitat, a Scarlet Badis can thrive for up to 4 to 5 years. This longevity, combined with their compact size, makes them a sought-after choice for aquarists who cherish both aesthetics and the natural life cycle of their aquatic pets.

Common Colour Varieties

The Scarlet Badis, true to its name, primarily sports a radiant scarlet hue that captivates observers. This bold red is interspersed with striking blue patterns, particularly evident in males, which makes them stand out even in densely planted tanks.

While the vibrant red-blue combination is the most common and recognisable, there are subtle variations, especially in the intensity of the red, depending on factors like diet, health, and breeding conditions. Females tend to have a more muted colouration, often leaning towards a pale pink or brownish hue.

This natural variation in shades adds to the intrigue and allure of keeping these small wonders in an aquarium.

Sexual Dimorphism

In the realm of the Scarlet Badis, distinguishing between males and females is relatively straightforward due to their pronounced sexual dimorphism. Males are the true showstoppers, boasting vibrant red and blue patterns that shimmer under the right lighting.

Their colour intensity often amplifies during breeding seasons or territorial displays. In contrast, females are more subdued in appearance. They lean towards paler hues, typically manifesting in light pink or even brownish tones, and lack the pronounced blue patterns seen in males.

Additionally, females are slightly smaller and possess a rounder body shape. Recognising these distinctions is crucial, especially for those keen on breeding or understanding their behaviours.

Behaviour & Temperament

The Scarlet Badis is a true gem in terms of temperament. Predominantly peaceful, these fish are, however, territorial, especially males defending their chosen spots. While they might display bouts of chasing, it’s rarely aggressive or harmful. They’re often observed lurking amongst plants, foraging for tiny prey.

Being shy by nature, they appreciate densely planted areas which offer refuge. Despite their retiring nature, their vibrant colours and subtle behaviours provide endless fascination, making them a delightful presence in any peaceful community aquarium.

Scarlet Badis Food & Diet

The Scarlet Badis is known for its selective feeding behaviour, which can sometimes pose a challenge for aquarists. Catering to its diet ensures vibrancy, health, and longevity.

Live Foods: This is the core of their diet. They have a particular fondness for:
- Daphnia: Small freshwater crustaceans.
- Micro-worms: Essential for providing necessary proteins.
- Brine Shrimp: Especially the newly hatched ones, which are tiny enough for them to consume.
Frozen Foods: A good alternative to live foods. However, ensure they are thawed properly before feeding.
- Bloodworms: Although larger, younger Scarlet Badis can eat smaller pieces.
- Cyclops: Tiny crustaceans that can be an occasional treat.
Processed Foods: While Scarlet Badis often shun traditional fish flakes or pellets, there are specialised nano pellets available that some might accept with time.
Feeding Frequency: Ideally, feed them once or twice a day but in small quantities to avoid overfeeding and maintain water quality.

Changes in Behaviour

For any aquarist, understanding the typical behaviours of your fish and being vigilant about changes is vital for their well-being. For the Scarlet Badis, here are some behavioural shifts to be aware of:

Lethargy: A sudden decrease in activity, where the fish stays at the bottom or hides constantly, may indicate illness or stress.
Loss of Appetite: While Scarlet Badis can be picky eaters, a prolonged refusal to eat is a cause for concern.
Erratic Swimming: Darting rapidly, swimming upside-down, or spinning can be signs of distress, disease, or water parameter imbalances.
Surface Gasping: Continuously swimming near the surface and appearing to gasp for air might suggest oxygen deficiency or water quality issues.
Scratching: If the fish rubs against objects, plants, or the substrate frequently, it might be experiencing irritation, often due to parasites.
Aggression: A sudden increase in territorial disputes or aggression towards tankmates could be due to overcrowding, breeding behaviour, or stress.
Colour Change: A noticeable fading or darkening of their vibrant hues, especially if rapid, might indicate stress, disease, or poor diet.
Clamped Fins: Fins held close to the body, rather than being fanned out, often signals discomfort or illness.
Isolation: While they are somewhat shy, if a Scarlet Badis isolates itself entirely from other tank inhabitants, it might be feeling unwell.

Always remember that a change in behaviour doesn’t necessarily mean illness. It could also be a response to environmental factors, such as water temperature, pH, or tank decorations. Regular observation, coupled with understanding their natural behaviour, will aid in differentiating between normal activities and potential signs of distress or disease.

Scarlet Badis Tank Mates

Can You Keep Scarlet Badis Together?

Yes, you can keep Scarlet Badis together, but there are certain considerations to keep in mind:

Territorial Males: Male Scarlet Badis are known for their territorial nature. If you’re planning to keep multiple males together, it’s essential to provide them with ample space and visual barriers, like plants or decorations, to establish their own territories. Without these provisions, there’s a likelihood of territorial disputes.
Females: Females are less territorial than males and can coexist more peacefully. You can have a higher female-to-male ratio in a tank to reduce the likelihood of male aggression.

Tank Mates for Scarlet Badis:

Scarlet Badis, due to their peaceful and somewhat shy nature, can coexist with a variety of small, non-aggressive fish and other aquatic creatures. Here are some ideal tank mates:

Small Tetras: Species like Neon Tetras or Ember Tetras are peaceful and won’t bother the Scarlet Badis.
Rasboras: The likes of Chili Rasboras or Boraras brigittae are good choices, given their calm temperament.
Pygmy Corydoras: These bottom dwellers are non-intrusive and will not compete with the Scarlet Badis for territory.
Dwarf Loaches: Such as the Kuhli Loach.
Shrimp: Small, non-aggressive varieties of shrimp, like Cherry Shrimp and Amano Shrimp, can coexist peacefully with Scarlet Badis. In fact, Scarlet Badis and shrimp can often be seen sharing the same space without issues.

Tank Mates to Avoid: Choosing the wrong tank mates can lead to stress, injury, or even the death of your Scarlet Badis. It’s best to avoid:

Large, Aggressive Fish: Species like Cichlids, larger Barbs, or aggressive Catfish can harm or stress the small Scarlet Badis.
Fin-Nippers: Fish like some types of Tetras (e.g., Serpae Tetras) can nip at the fins of Scarlet Badis, causing injury and stress.
Predatory Fish: Fish that prey on smaller species, such as certain larger Bettas, should be avoided.
Large or Aggressive Shrimp: Some larger shrimp species might be territorial or aggressive, potentially posing a threat to the Scarlet Badis.
Sharks: Although they’re often sought after for their striking appearance, certain freshwater sharks like the Rainbow Shark and Black Shark are territorial and can display aggression, especially in confined spaces. Their size and territorial nature make them unsuitable tank mates for the Scarlet Badis.

Breeding

Breeding Scarlet Badis requires attention to detail, especially when it comes to water parameters and diet. However, with dedication, you can successfully raise a new generation of these beautiful fish.Here’s a breakdown of the breeding habits and steps to encourage reproduction:

Total Time: Approximately 7-13 weeks

1: Tank Conditions:

Before you begin, it’s essential to establish the correct breeding environment. This includes:
* Soft water with a pH of around 6.5 to 7.
* A temperature ranging from 23°C to 26°C.
* Densely planted aquarium, offering hiding and spawning sites.

2: Sexual Dimorphism:

Males are more vibrantly coloured, typically brighter red with distinctive vertical blue stripes. Females are plainer with a more muted colour palette.

3: Diet:

Before breeding, both males and females should be fed a rich diet, including live or frozen foods such as daphnia, brine shrimp, and micro-worms to induce spawning.

4: Spawning Process:

Males will typically claim a territory, usually around a particular plant or hiding spot, and then display to attract females. Once a female is interested, she’ll approach the male’s territory. After a series of dances and displays, the female will deposit her eggs, and the male will fertilise them.

5: Egg Care:

Post-spawning, males may become protective of the territory where the eggs are. The eggs, usually laid on the undersides of leaves or in crevices, will hatch in about 2-3 days.

6: Fry Care:

Once hatched, the fry can be incredibly tiny and will require microscopic food sources. Infusoria (a mix of microscopic organisms) is the ideal initial food. As they grow, they can be shifted to micro-worms and newly hatched brine shrimp.

7: Separation:

It might be a good idea to have a separate breeding tank or to remove the adult Scarlet Badis after breeding. This ensures the safety of the fry as, in some cases, adult fish may predate on their young.

8: Growth:

With proper care, the fry will start showing colours in a few weeks and can be introduced to the main tank once they’re large enough not to be seen as prey by other inhabitants.

Should You Keep The Scarlet Badis?

The Scarlet Badis is a captivating gem in the freshwater aquarium world. Boasting vibrant hues and a calm disposition, they offer a visual treat and make an excellent choice for both novice and seasoned aquarists. While they require specific water parameters and a well-structured habitat, their unique behaviour and stunning appearance more than compensate for the care they demand.

If you’re seeking a petite, colourful fish that’s both engaging and peaceful, the Scarlet Badis is undoubtedly worth considering. However, ensure you provide them with an appropriate environment, the right tank mates, and a varied diet. If catered to properly, this dazzling species promises an enriching and delightful aquarium experience.
