There are several aquarium pets, but betta fish or Siamese Fighting Fish are among the most favored by people worldwide. The beauty that lies in their fins, colors, and personality makes them less than just "fish" and gives people the impression that they are tiny aquatic characters. But behind the beauty lies a vibrant history of this species, particular behavior, and particular needs every owner should know.
What Is a Betta Fish?
Originally bred in Southeast Asia, bettas are small freshwater fighter fish. They were cultivated for aggressiveness and allowed to compete territorially. Today, however, most bettas are known for their extravagant colors, flowing fins, and interactive nature, making them popular as both display and companion fish.

Big personality: each betta behaves differently-some curious, some shy, some bold

These fish are not just beautiful, but in fact they are also quite intelligent and recognize their owners.
Where Do Bettas Live in Nature?
Each warm, shallow waters in Southeast Asia comes from such countries as:
-
Thailand
-
Indonesia
-
Vietnam
-
Cambodia
-
Laos
-
Bettas' Natural Habitat
Wild bettas live in:
- Rice paddies
-
Floodplains and shallow ponds
-
Slow-moving streams
-
Warm wetlands full of plants
These waters are calm and low-flow, which explains why bettas dislike strong currents. They have a special breathing organ called a labyrinth organ, allowing them to breathe air from the surface - this helps them survive in oxygen-poor water.
Ideal Tank Setup & Environment
Bettas come from shallow waters, but that doesn't mean they don't require the space: they'd need a tank, not a bowl.
Requirement Ideal Range
Tank Size: Minimum 10 litres (preferably 15 - 30L)
Temperature: 26°C-28°C (warm water is essential)
Filter: Gentle flow, no strong currents
Heater: Yes - bettas are tropical fish
Water pH: 6.5-7.5
Lighting: Moderate, with day-night cycle
Decor: Live plants, caves, smooth décor (no sharp edges)
Why Bowls Are Not Recommended
-
No space to swim
-
Water quickly becomes dirty and toxic
-
No heating = temperature shock
Shortens lifespan
A proper tank could drastically improve their health and their then vibrancy of color.
What Are Betta Fish's Diets?
Bettas are carnivores. The diet must contain high protein and animal-based ingredients-they can't live with plant-only foods.
Suggested Foods
- Pellets made specially for bettas
- Fresh or frozen brine shrimp
- Bloodworms
Feeding tip: these fish have small stomachs-about the size of their eye. Tiny meals twice a day will suffice.
Betta Behavior & Personality
Bettas are quite expressive. Their fins will flare out to demonstrate when they are excited, show defensiveness, or otherwise assert dominance. They might also check out, patrol, or interact with their owner through the glass.
Behaviors Most Common Explained
Flaring: showing dominance or excitement
Resting on leaves: especially on "betta hammocks"
Bubble nest: a male will make these in preparation for future eggs. This is evidence of confidence.
Following movement: they recognize their owners
Jumping: bettas can jump! Always keep a tank lid.
Tank Mates: Can Bettas Live With Others?
Yes-all it takes is the right tank mates. Of course, never put in a single tank another male betta.
Approved Tankmates
Nerite snails-Mystery snails
Amano shrimps
Ghost shrimps
Shy schooling fish like the Ember Tetra.
Bottom dweller: Corydoras
Avoid
Fin-nippers (Tiger Barbs)
Bright long-finned fish

Clamped fins
Loss of color
White spots (ich)
Torn fins (fin rot)

Yes, betta fish are considered beginner-friendly, but they still need proper space, warm water, a filter, and the right diet to stay healthy and colorful.
2. Can a betta fish live in a bowl?

8. How long do betta fish live?
With proper care, bettas live 3–5 years, sometimes longer (up to 6+ years) with excellent tank conditions.
9. Why is my betta’s color fading?
Fading color may be due to stress, poor water quality, cold temperature, illness, or diet issues. Check water parameters and tank setup immediately.
