Freshwater Aquarium Fish, Tropical Fish & Goldfish

Explore freshwater aquarium fish at The Tech Den Australia, from colourful tetras and guppies to discus, angelfish, cichlids and goldfish. Browse the catalogue to plan your aquarium, then check availability and purchasing arrangements with the store. Fish listings are predominantly marked no online purchases or in-store pickup only.

Tropical fish and community aquarium options

Browse neon, cardinal and rummy nose tetras, rasboras, danios, guppies, mollies, platies and swordtails. The range also includes gouramis, male and female bettas, loaches and other tropical fish. Suitability for a community aquarium depends on the individual species and your existing livestock, not simply its inclusion in this collection.

Discus, angelfish and cichlids

Explore discus and angelfish varieties, dwarf cichlids such as Apistogramma and rams, and a broad selection of African and American cichlids. Compare adult size, temperament, water requirements and aquarium space before choosing tank mates.

Catfish, plecos and bottom-dwelling fish

Find Corydoras, bristlenose catfish, whiptails, Synodontis and L-number plecos, alongside selected loaches. These fish have different feeding and habitat needs; do not rely on algae or leftover food as a complete diet.

Goldfish, rainbowfish and Australian natives

Browse comets and fancy goldfish varieties including fantails, orandas, ranchus and ryukins. The collection also features rainbowfish, blue-eyes and selected Australian native fish, with species-specific space and care requirements.

Shrimp, snails and other aquatic livestock

Selected shrimp, snails and other aquatic livestock are also listed in this collection. Check their individual requirements and compatibility rather than treating them as interchangeable additions to a fish tank.

Plan your aquarium before choosing fish

Allow for adult size and swimming space, not just the size at purchase.
Compare temperature, pH and hardness requirements for each species.
Check temperament, feeding needs and whether fish require groups or a species-specific setup.
Prepare and monitor your aquarium before adding livestock, and ask for species-specific acclimatisation guidance.

Some catalogue species need specialised or brackish-water conditions. A listing in this collection does not mean every animal suits a standard freshwater community aquarium.

In-store purchasing and availability

Check individual listings for no-online-purchase and pickup-only notices. Contact The Tech Den before visiting to confirm the species, size and variety you are looking for, and ask the team for help matching livestock to your setup.
