Buy Tropical Fish Online in Australia

Tropical freshwater fish are popular with Australian fishkeepers because of the wide variety of colours, sizes, behaviours and personalities available.

They can be used to create peaceful community aquariums, planted tanks, species-focused displays and colourful aquascapes. However, not every tropical fish has the same requirements. Tank size, water conditions, social behaviour and compatibility should always be checked before purchasing.

Our livestock availability changes regularly. Browse the products above to see the tropical fish currently available or explore our complete live aquarium fish collection.

Tropical Fish for Community Aquariums

A community aquarium contains compatible fish that can live together under similar conditions. A well-planned community tank may include species that occupy different areas of the aquarium, creating activity at the surface, through the middle and around the bottom.

Popular community aquarium fish can include:

• Tetras
• Guppies
• Corydoras Catfish
• Selected Gouramis
• Platies
• Swordtails
• Rasboras
• Selected Barbs
• Small freshwater Catfish

Compatibility depends on the particular species. Fish described as community fish can still differ in adult size, activity, fin-nipping behaviour, preferred water conditions and social requirements.

How to Choose Tropical Aquarium Fish

It can be tempting to select fish based mainly on colour or appearance. A healthier aquarium starts with choosing species that suit the environment you can provide.

Before adding tropical fish, consider:

• Expected adult size
• Minimum aquarium dimensions
• Preferred water temperature
• Suitable pH and water hardness
• Temperament and territorial behaviour
• Schooling or group requirements
• Compatibility with existing livestock
• Diet and feeding behaviour
• Swimming level and activity
• Filtration and water-quality requirements

Always plan around the fish’s adult size and behaviour rather than simply its size at the time of purchase.

Schooling Tropical Fish

Many tropical fish naturally live in groups. Tetras, Rasboras, Danios and several Barb species generally display more confident and natural behaviour when maintained in suitable numbers of their own kind.

The correct group size varies between species. A larger school also requires enough aquarium volume, swimming space and filtration capacity to support the combined bioload.

Schooling fish can be especially effective in planted aquariums, where the group creates movement and colour against live aquarium plants and natural aquascaping.

Tropical Fish for Beginners

Some tropical freshwater fish can be suitable for newer fishkeepers when provided with a properly cycled aquarium, stable water conditions and compatible tank mates.

Depending on the aquarium and local water conditions, beginner-friendly options may include:

• Guppies
• Platies
• Swordtails
• Selected Tetras
• Corydoras
• Selected smaller Gouramis
• Some Danios and Rasboras

No aquarium fish is completely maintenance-free. New fishkeepers still need to cycle the aquarium, test the water, avoid overstocking and perform regular maintenance.

Aquarium Size for Tropical Fish

The right aquarium size depends on the species, expected adult size, activity level and number of fish being kept.

Some small species can suit relatively compact aquariums when maintained correctly. Larger Gouramis, Angelfish, Silver Dollars and active schooling fish need considerably more swimming space.

A longer aquarium may provide more useful swimming room than a taller aquarium of similar volume. Explore our aquariums and complete fish tank kits when planning a new tropical setup.

Do Tropical Fish Need a Heater?

Most commonly kept tropical freshwater fish require consistently warm water. A suitable thermostatically controlled aquarium heater is generally recommended when room temperature cannot reliably maintain the range needed by the species.

Different tropical fish have different temperature preferences. Check the requirements of every species before combining them, rather than selecting one temperature for the aquarium without considering its inhabitants.

A thermometer should be used to monitor the actual water temperature because heater settings and aquarium temperatures can differ.

Filtration and Water Quality

Effective aquarium filtration helps process fish waste and supports stable water conditions. The filter should be suitable for the aquarium volume, stocking level and type of fish being kept.

A tropical aquarium should be fully cycled before fish are introduced. Regular testing and partial water changes help manage ammonia, nitrite, nitrate and other water-quality factors.

Add new fish gradually rather than fully stocking a new aquarium at once. This gives the biological filter time to adjust to the increased bioload.

Feeding Tropical Fish

A varied, species-appropriate diet helps support healthy growth, colour and overall condition. The right food depends on whether the fish is primarily omnivorous, herbivorous or carnivorous and where it feeds in the aquarium.

Suitable foods may include:

• Quality tropical flakes
• Floating or slow-sinking pellets
• Micro pellets for smaller fish
• Sinking foods for bottom dwellers
• Algae-based foods for suitable species
• Appropriate frozen or live foods

Browse our tropical fish food or complete aquarium fish food range to find foods suited to different freshwater species.

Feed only an appropriate amount and remove uneaten food where practical. Overfeeding can contribute to poor water quality and unnecessary algae growth.

Tropical Fish Compatibility

Not every tropical fish can live together successfully. Before introducing a new species, compare it with your existing livestock.

Important compatibility factors include:

• Adult body size
• Aggression and territorial behaviour
• Fin-nipping tendencies
• Predatory behaviour
• Preferred water conditions
• Swimming activity
• Schooling or group requirements
• Feeding behaviour and competition

Avoid combining very small peaceful fish with large predatory species. Slow-moving or long-finned fish may also be unsuitable companions for active fin-nipping species.

If you are unsure whether a fish will suit your aquarium, please contact Aquaholics before ordering.

Planted Tropical Aquariums

Many tropical fish can thrive in planted aquariums. Live plants can provide shelter, visual barriers, spawning areas and a more natural-looking environment.

Planted aquariums are especially popular for Tetras, Rasboras, Gouramis, Corydoras and other peaceful community fish. However, plant and fish compatibility still matters because some species may dig around, uproot or eat particular plants.

Frequently Asked Questions About Tropical Fish

What are good tropical fish for beginners?

Guppies, Platies, Swordtails, selected Tetras, Corydoras and some Gouramis can be suitable for beginners when kept in a properly cycled aquarium with stable water conditions and appropriate tank mates.

Do tropical fish need a heater?

Most tropical aquarium fish require consistently warm water. A suitable aquarium heater is generally recommended unless the aquarium naturally remains within the temperature range required by every species being kept.

Can different tropical fish live together?

Many tropical fish can live together in a community aquarium, but compatibility depends on temperament, adult size, water requirements, aquarium dimensions and social behaviour. Every species should be checked before it is introduced.

How many tropical fish can I keep?

There is no single stocking number that suits every aquarium. The appropriate number depends on tank volume, fish species, adult size, filtration, swimming space, group requirements and maintenance.

Do tropical fish need to live in groups?

Some tropical fish are schooling or social species that should be maintained in suitable groups. Other species may live alone, in pairs or within carefully planned social structures. Check the requirements of each species before purchasing.

Should I quarantine new tropical fish?

Quarantining new livestock before adding it to an established aquarium is good fishkeeping practice where suitable quarantine facilities are available. It allows new fish to be observed separately before joining the main aquarium.
