Alien Betta Size & Lifespan

The lifespan of an alien betta fish is typically four years in captivity. If you give them the proper care and feeding, they can grow from 2 to 3 inches long.

Alien Betta Fish Types

There are a lot of different alien betta morphs to choose from. While not as common as standard bettas, you can find them in pet stores, online retailers, and fish shows.

Alien Plakat Betta

The three common varieties of alien betta fish are:

  • Plakat Alien Betta Fish: Plakat bettas are a shorter-finned subtype of betta that has a big, powerful physique and enormous fins with small jaws. These fish dwell in rice paddies and are bred for their combat skills, but they have the same markings as other Alien Bettas.
  • Green Alien Betta Fish: These beautiful bettas have a green body with black spots, similar to a Leopard or Jaguar. Unfortunately, these fish don’t live in the wild and are only bred in captivity.
  • Copper Alien Betta Fish: Copper aliens have a coppery hue with patterns all over their bodies. These exotic fish don’t dwell in the wild and have been bred by man for their beautiful colors. Because of this, they can be pretty expensive to purchase, but many online breeders sell them.


In the wild, alien bettas inhabit warm, shallow rivers with dense vegetation, where they consume mosquito larvae, bugs, and other small invertebrates.

In your home aquarium, it’s fascinating to watch your fish navigate through a densely planted aquarium, occasionally pausing to rest on a leaf before resuming its food search!

To replicate this scenario, you may utilize living plants that can withstand the high temperatures bettas prefer, such as amazon swords, java moss, and java fern.

Also, these plants are long-lasting, low-maintenance, and require little carbon dioxide or fertilizer.

As for substrate, you can use anything from gravel to sand to pebbles. Just make sure it is smooth, so it doesn’t damage your betta’s delicate fins.

If you want a more natural approach, you can use driftwood to create hiding places and shelter.

Not only is driftwood visually appealing, but it also slowly releases tannins into the water column. These humic acids lower the pH level and provide valuable minerals that strengthen your fish’s immune system.

Alien Betta Fish Compatibility

Alien Betta

Alien betta fish isn’t the best community fish. They are aggressive and territorial by nature, so they don’t do well with other fish. So, if you want to keep more than one alien betta in a tank, you will need a very large tank so they can each have their own space.

Also, it would be best if you chose other peaceful fish with similar care requirements to keep with your alien betta. Some compatible fish options include the following:

  • Dwarf Gouramis
  • Livebearers
  • Tetras
  • Smaller Barbs
  • Danios
  • Corydoras
  • Clown Pleco
  • Dwarf Otocinclus
  • Rubber Pleco
  • Kuhli Loaches
  • Snails and larger shrimp

  • Dwarf Shrimp
  • Other Betta Males
  • Dwarf Cichlids (except in medium-sized or larger tanks)
  • Blue Rams
