Alien Betta Fish

Alien Betta Fish are a stunning and sought-after freshwater aquarium species that have captivated both experienced and novice aquarists alike. Known for their dramatic appearance and vivid colors, these remarkable fish are prized for their ability to make a striking centerpiece in any aquarium. This comprehensive guide will cover everything you need to know about Alien Betta Fish, including their origins, appearance, care requirements, tank setups, and breeding.

Species Overview

The Alien Betta Fish is a beautiful and unique freshwater species that is not found in the wild. These fish are specially created by crossing several wild Betta species, including Betta splendens, Betta smaragdina, Betta stiktos, and Betta mahachaiensis. The exact origins of Alien Betta Fish remain unknown, but they have gained immense popularity in the aquarium trade due to their striking appearance and vibrant colors.

Types and Varieties

Alien Betta Fish are available in a range of colors and varieties. Generally, these fish are categorized by their overall coloration and fin types. For example:

  • Green Alien Bettas: Featuring a vivid green coloration.
  • Blue Alien Bettas: Displaying a striking blue hue.
  • Copper Alien Bettas: Exhibiting a unique copper color.

In addition to these color variations, Alien Betta Fish can also be found in a short-finned variety known as Plakat Alien Bettas. These fish have large bodies, smaller jaws, and shorter fins compared to their long-finned counterparts. Regardless of the type you choose, all Alien Betta Fish have a captivating and distinct appearance that makes them highly sought-after by aquarists.

Alien Betta Fish Appearance

The Alien Betta Fish’s beauty lies in their extraordinary coloration and fin structure. They are available in a variety of colors, with most featuring a dark black or brown base color. The metallic scales on their bodies create a stunning contrast, exhibiting an iridescent sheen that can shimmer in a spectrum of hues. This combination of metallic color with a dark backdrop creates the alien-like appearance that inspired their name.

Their fins are equally impressive, boasting dramatic stripes and spots that are impossible to ignore. Alien Bettas share a similar body shape with other Betta species, with sleek bodies, rounded heads, and upturned mouths. Their caudal fins are rounded and expansive, while their anal fins stretch along most of the fish’s underside, creating a visually striking wall of color.

Male Alien Bettas are typically more vibrant and have more dramatic fins than females. However, females are also quite beautiful, featuring more color than other female Betta varieties and plumper bodies compared to males.

Lifespan and Size

With proper care and a suitable environment, Alien Betta Fish can live for an average of four to five years. Their lifespan can be influenced by factors such as genetics, diet, and water conditions. Maintaining optimal living conditions and providing a high-quality diet can help ensure a longer, healthier life for your Alien Betta.

In terms of size, Alien Betta Fish are relatively small, with adults typically reaching two to three inches in length. Their size can also be affected by factors such as genetics and the quality of care provided.

Alien Betta Fish Care

Caring for Alien Betta Fish is not as challenging as one might think. They are known to be hardy and adaptable, making them suitable for both experienced and novice aquarists. However, like any other fish species, they have specific care requirements that must be met to thrive in captivity. The following sections provide essential care guidelines to help maintain a healthy and comfortable environment for your Alien Betta Fish.

Tank Size

Due to their small size, Alien Betta Fish do not require a large tank. They are not particularly active swimmers, so a spacious swimming area is not necessary. A minimum tank size of five gallons is recommended for a single Alien Betta. If possible, consider providing a larger tank, as smaller tanks can be more challenging to maintain stable water parameters and may not accommodate tank mates.

Water Parameters

Alien Betta Fish share similar environmental preferences with their wild Betta counterparts, requiring warm temperatures and slightly acidic water. To ensure the health and well-being of your Alien Betta, aim to replicate the conditions found in their natural habitat. This includes providing a stable water temperature, pH, and hardness within the following ranges:

  • Water temperature: 75-85 degrees Fahrenheit (78-80 degrees is optimal)
  • pH levels: 5.0-7.0 (6.5 is ideal)
  • Water hardness: 5-20 dGH

Tank Setup

When setting up your Alien Betta Fish’s tank, you have the freedom to choose a variety of designs and decorations. While some aquarists prefer a minimalist or modern setup, a natural-looking environment with plants and hiding spots can provide better enrichment for your fish.


Alien Betta Fish are not particularly fussy when it comes to substrate, so you can choose the type that best suits your preferences and the needs of your tank. Gravel or sand typically works well, especially if you plan to add live plants. To enhance the vibrancy of your Alien Betta’s colors, consider using a black-colored substrate.

Plants and Decorations

While Alien Bettas do not require densely planted tanks, adding a few live plants can create a more natural environment for your fish. Suitable plant options include java fern, java moss, and Amazon swords. Position the plants towards the back of the tank, leaving the center open for swimming space.

In addition to plants, consider incorporating driftwood and smooth rocks into your tank setup. Driftwood not only adds visual appeal but also releases tannins that help lower water acidity, creating a more suitable environment for your Alien Betta Fish.

Filtration and Water Movement

To maintain clean and stable water conditions, it is essential to install an appropriately sized filter in your Alien Betta’s tank. Sponge filters are a popular choice, as they can help prevent strong currents that may stress your fish. Alien Bettas prefer calm water with low dissolved oxygen, so avoid using filters that produce strong water flow.

Diet and Feeding

Alien Betta Fish are opportunistic micro predators that thrive on a high-protein diet. In the wild, they primarily consume insects and their larvae. While they can be trained to eat commercial Betta pellets, a diet rich in live or frozen foods can help bring out the best in your Alien Betta.

Some suitable food options for your Alien Betta include brine shrimp, daphnia, bloodworms, and tubifex worms. A varied diet can help ensure your fish receives all the necessary nutrients for optimal health and coloration.

Behavior and Temperament

Although Alien Betta Fish are known to be less aggressive than other Betta species, they can still exhibit territorial and aggressive behaviors. Males, in particular, may view other fish as threats and engage in fights. They can even become aggressive towards their own reflection, flaring their gills and twitching in an attempt to intimidate potential rivals.

When kept alone or with compatible tank mates, Alien Bettas are generally calm and peaceful. They enjoy exploring their tank and displaying their stunning colors and finnage.

Tank Mates

While it is possible to house Alien Betta Fish with other species, careful consideration must be given to their tank mates. Male Alien Bettas should be kept separate from other males, as they are highly territorial and may fight. Female Alien Bettas, on the other hand, are less aggressive and can be housed in a small group with one male.

Suitable tank mates for Alien Bettas include peaceful, similarly-sized fish species, such as:

  • Harlequin Rasboras
  • Corydoras Catfish
  • Neon Tetras
  • Otocinclus Catfish

Avoid aggressive or fin-nipping species, as your Alien Betta may not be able to evade faster or larger fish. Always monitor your community tank closely and be prepared to remove any fish that display aggressive or incompatible behaviors.

Breeding Alien Betta Fish

Breeding Alien Betta Fish requires a bonded pair that has already been living together. Introducing a male and female without prior interaction is unlikely to result in successful spawning. To encourage breeding, provide a high-protein diet and raise the water temperature slightly.

During the breeding process, the male Alien Betta will create a bubble nest in a corner of the tank, often using plant leaves to gather bubbles. The female will then release her eggs, which the male will collect, fertilize, and place in the bubble nest. The male will guard the eggs for approximately 48 hours until they hatch. At this point, it is crucial to remove the male to prevent him from eating the fry.

Once the fry become free-swimming, they can be fed powdered food, infusoria, or baby brine shrimp to support their growth and development.

Alien Betta Fish are a stunning and unique addition to any aquarium. With their captivating appearance and fascinating behaviors, they are sure to be a conversation starter and a source of joy for any aquarist. By following the care guidelines outlined in this comprehensive guide, you can provide a healthy and comfortable environment for your Alien Betta Fish to thrive.
