Betta Fish

Shop colourful Betta Fish online at Aquaholics Online.

Also known as Siamese Fighting Fish, Bettas are one of the most recognisable freshwater aquarium fish. They are famous for their vibrant colours, flowing fins and individual personalities, with varieties ranging from classic reds and blues to striking metallic, marble and multicolour patterns.

Our Betta range may include male and female Bettas in a variety of colours and fin types depending on availability.

Betta Fish for Freshwater Aquariums

Betta Fish can make fantastic feature fish for a well-planned freshwater aquarium.

Although they are sometimes sold for very small containers, Bettas benefit from a properly heated and filtered aquarium with enough room to swim, explore and rest.

A good Betta setup should provide:

• Stable warm water
• Gentle filtration
• Live or soft aquarium plants
• Resting areas near the surface
• Open swimming space
• A secure aquarium lid

Bettas can jump, so keeping the aquarium covered is recommended.

Male Betta Fish

Male Bettas are especially popular for their strong colouration and long, flowing fins.

They are also highly territorial towards other male Bettas and should not normally be kept together in the same aquarium.

Many males are best maintained as a single feature Betta or with carefully selected peaceful tank mates in a suitably sized aquarium.

Female Betta Fish

Female Bettas generally have shorter fins than males but can still display impressive colours and patterns.

Their temperament varies considerably between individual fish.

While experienced aquarists sometimes maintain groups of females in carefully designed aquariums, aggression can still occur and this type of setup requires close monitoring and plenty of space and cover.

Betta Tank Mates

Some Bettas can live successfully with peaceful community fish, while others are better kept alone.

Possible tank mates may include:

• Corydoras
• Small peaceful Tetras
• Rasboras
• Bristlenose Catfish
• Peaceful bottom-dwelling fish
• Some freshwater shrimp and snails

Compatibility always depends on the temperament of the individual Betta.

Avoid aggressive fish, persistent fin nippers and other male Bettas.

Betta Fish & Live Plants

Bettas are particularly well suited to planted aquariums.

Live plants provide shelter, resting areas and a more natural environment while helping create visually impressive Betta displays.

Suitable plants can include:

• Anubias
• Java Fern
• Cryptocoryne
• Java Moss
• Floating plants
• Other soft-leaved aquarium plants

Broad leaves positioned closer to the surface can provide convenient resting areas.

Water Temperature

Betta Fish are tropical fish and should be kept in consistently warm water.

A thermostatically controlled aquarium heater is generally recommended in Australian homes, particularly during cooler months or where room temperatures fluctuate.

Avoid sudden temperature changes.

Filtration for Betta Fish

Bettas benefit from clean, filtered water but generally prefer relatively gentle water movement.

Strong currents can make swimming difficult, particularly for long-finned varieties.

Small internal filters, sponge filters or adjustable filters can work well when the flow is appropriate for the aquarium.

Regular water changes remain important even when filtration is used.

Feeding Betta Fish

Bettas are primarily carnivorous and benefit from a high-quality diet formulated for tropical or Betta Fish.

Suitable foods can include:

• Betta pellets
• Quality micro pellets
• Frozen bloodworms
• Brine shrimp
• Daphnia
• Suitable insect-based foods

Feed sensible portions and avoid overfeeding.

A varied diet can help support good condition and colouration.

Betta Fish Behaviour

One of the reasons Bettas are so popular is their personality.

Individual fish can be curious, interactive and surprisingly responsive to activity around the aquarium.

Bettas also regularly visit the water surface because they possess a specialised labyrinth organ that allows them to breathe atmospheric air.

This is normal Betta behaviour.

Betta Aquarium Setup

A good Betta aquarium can combine:

• Gentle filtration
• Aquarium heater
• Live plants
• Driftwood
• Smooth rocks
• Soft substrate
• Floating plants
• Open swimming areas

Avoid sharp decorations or rough artificial plants that could damage delicate fins.

A planted Betta aquarium can also make an excellent small aquascape.

Betta Fish Colours & Fin Types

Betta Fish have been selectively bred into an enormous variety of appearances.

Depending on availability, Bettas may display:

• Red
• Blue
• Yellow
• White
• Black
• Metallic
• Marble
• Multicolour patterns

Fin types can also vary significantly between individual fish and varieties.

Because each Betta is unique, colour and pattern may vary from representative product images.

Are live plants good for Bettas?
