Why choose the CW27 Hi Fin?

The CW27 Hi Fin is one of the most distinctive Corydoras ever introduced into the aquarium hobby. Closely related to Corydoras brevirostris, it is instantly recognised by its exceptionally tall dorsal fin, elegant spotted body and brilliant reflective patch behind the head. This unique combination makes it one of the most sought-after Corydoras among collectors. :contentReference[oaicite:0]{index=0}

Like all Corydoras, CW27 spends its day actively searching the substrate for food using sensitive barbels. They are highly social fish that become increasingly confident when kept in groups, often foraging together before resting beneath driftwood or broad-leaved plants.

Although rare, their husbandry is very similar to other Corydoras species. Given clean water, a soft substrate and quality nutrition, they are hardy, active and incredibly rewarding fish to own. :contentReference[oaicite:1]{index=1}

  • Long-lived and hardy when properly maintained

Care made simple

  • Temperature: 22–27°C
  • pH: 6.0–7.5
  • Diet: Premium sinking pellets, Corydoras wafers, frozen bloodworms, blackworms, brine shrimp and quality live foods
  • Water: Clean, mature, highly oxygenated and well-filtered
  • Setup: Fine sand substrate, driftwood, leaf litter, dense plants and open foraging areas

  • Peaceful Apistogramma
  • Rainbowfish
  • Bristlenose Plecos
NTA Insight:
The Hi Fin dorsal isn't just a novelty—it completely changes the look of the fish. When a mature male raises that tall sail-like fin while swimming with a school, it's one of the most impressive sights you'll see in a Corydoras aquarium. Because they're uncommon and often expensive, we recommend housing them in a mature aquarium where excellent water quality and a soft sandy substrate allow them to thrive.

FAQ

What makes CW27 different from Corydoras brevirostris?

CW27 closely resembles Corydoras brevirostris but is distinguished by its dramatically taller dorsal fin and brighter reflective "glow spot" behind the head. These features are what make it so desirable among Corydoras collectors. :contentReference[oaicite:2]{index=2}

How many CW27 Hi Fin Corys should I keep?

Like all Corydoras, they should be kept in groups of at least six. Larger schools of 8–10 or more encourage natural schooling behaviour and help the fish become more confident. :contentReference[oaicite:3]{index=3}

Can they live with shrimp?

Yes. Adult Neocaridina and Caridina shrimp generally coexist well with CW27 Corys. Dense mosses and plants provide excellent protection for young shrimplets.

Do they eat algae?

No. They are not algae eaters. Although they consume uneaten food from the substrate, they require a varied diet of quality sinking foods, frozen foods and occasional live foods.

Are CW27 Hi Fin Corys suitable for beginners?

Their care is straightforward, but because of their rarity and value, they're best suited to aquarists with a mature, stable aquarium who can consistently provide excellent water quality. :contentReference[oaicite:4]{index=4}

    Live Arrival & Ordering FAQ

    Why do livestock prices sometimes change?

    Unlike manufactured products, fish and shrimp continue to grow and develop over time. Their value changes as they increase in size, develop colour, or become breeding pairs.

    Our prices are based on the current size, quality and availability of each specimen. While pricing often remains stable for around 3–4 months, it may be updated at any time to reflect these changes.

    We always aim to offer healthy, high-quality livestock at fair and competitive prices.

    Do you offer a live arrival guarantee?

    Yes. All livestock is covered by our Live Arrival Guarantee.

    In the rare event of DOA, please contact us promptly with clear photos of the livestock in the original unopened bag.

    Please review our full DOA and store policies before purchase.

    Can you ship to all states in Australia?

    No. Due to state restrictions, we cannot ship livestock or live plants to WA and TAS.

    What should I check before ordering?

    Before placing an order, make sure:

    • Your tank is fully cycled and stable
    • Your aquarium has enough space for the species
    • Your current livestock are compatible in temperament, size, and requirements
    • Your water parameters, habitat, and temperature suit the species
    • You are not adding too many fish at once
    What should I expect when my fish arrives?

    It is normal for fish, shrimp, or snails to look pale, stressed, or less active after shipping.

    This is temporary. Most livestock will settle and regain colour within a few days.

    How long does it take for fish to settle in?

    Most livestock will take 3–7 days to fully adjust to their new environment.

    Should I feed my fish immediately after arrival?

    No. We recommend waiting 24 hours before feeding to allow them to settle.

    If you already have fish in your tank, feeding them before introducing new arrivals can help reduce stress.

    Why do fish sometimes struggle after being added to a tank?

    In most cases, issues are caused by tank conditions, not shipping.

    • Uncycled or unstable tanks
    • Poor water parameters
    • Overstocking
    • Unsuitable tank mates
    What is Nano Tanks Australia’s main tip for new livestock?

    Most livestock losses happen in immature or unstable tanks, not during shipping.

    If your setup is not fully established, the risk to new arrivals is significantly higher.

    Not sure if this fish is right for your setup?

    If you are unsure whether this species suits your setup, contact us before ordering and we’ll help point you in the right direction.
