Choosing the Right Species

Every species in this collection has different care requirements. Some are ideal for peaceful community aquariums, while others are best kept in species-only setups. We recommend reading each product description carefully to ensure your new fish is compatible with your aquarium.

Tank Size

Tank requirements vary considerably depending on the species. Always refer to the individual product page for minimum aquarium recommendations.

Water Parameters

Temperature, pH and water hardness vary between species. Stable, fully cycled aquariums are essential for keeping rare fish healthy and stress-free.

Aquascaping

Many uncommon species appreciate heavily planted aquariums with driftwood, rocks and natural hiding places. Replicating their natural habitat helps reduce stress and encourages normal behaviour.

Feeding

Feeding requirements vary between species. Some accept prepared foods immediately, while others require frozen or live foods before transitioning to pellets.

  • Premium pellets
  • Frozen bloodworms
  • Brine shrimp
  • Daphnia
  • Blackworms
  • Species-specific diets where required

Things to Consider

Rare Fish FAQs

Why are these fish considered rare?

Many are imported infrequently, originate from specialised breeders or are produced in relatively small numbers compared to common aquarium species.

Are rare fish more difficult to keep?

Not necessarily. Some, like Pea Puffers, have specialised requirements, while others are just as hardy as many common community fish. Always read the individual care information before purchasing.

Will these fish always be available?

No. Many species arrive only once or twice each year, while others depend on seasonal imports or successful breeding projects.

Can rare fish live in community aquariums?

It depends on the species. Some make excellent community fish, while others require species-only aquariums or carefully selected tank mates.

How often is this collection updated?

We regularly add new and unusual species whenever they become available, so it's worth checking back often if you're looking for something special.
