Lionfish naturally hold position around reef ledges, caves and coral heads, often resting during the day and hunting small fish or crustaceans when food is available. Natural origin for this listing is Indo-Pacific reefs, coral heads, caves, ledges and sheltered reef slopes. In captivity, the aquarium should recreate the security of reef structure with caves, ledges, open turning space and excellent filtration. These fish produce more waste than small community species, so oxygenation, protein skimming and stable water quality are critical.

Peacock Volitan Lionfish should show clear eyes, full body condition, intact fins and a strong feeding response. Lionfish display broad pectoral fins, dramatic dorsal spines and striped or patterned bodies. Their slow, deliberate movement gives them a commanding presence. Adult size is generally 35–38 cm, so the fish should never be purchased only for its current size. Colour, pattern and behaviour are usually best displayed once the fish has a secure territory and is feeding confidently.

Temperament is best described as Predatory but generally calm; will eat small fish or shrimp. Compatibility must be planned carefully. Suitable tank mates are generally robust marine fish that are too large to be swallowed and confident enough to feed, such as larger tangs, rabbitfish, large wrasse, robust angelfish, suitable triggers, groupers or other predators depending on the species. Avoid tiny fish, small ornamental shrimp, delicate timid species and anything that can fit into the mouth. For triggerfish and larger predators, also consider biting behaviour, rock movement and aggression at feeding time.

Feed as a Carnivore; frozen prawn, fish flesh, squid, krill, silversides and other meaty marine foods. Avoid long-term freshwater feeder fish. Use marine-based foods rather than freshwater feeder fish, as freshwater feeders are poor long-term nutrition and can contribute to health problems. Offer appropriately sized portions several times weekly or daily depending on the species, age and body condition. Predatory fish should be trained to accept frozen or prepared foods where possible. Feeding tongs are useful for eels, lionfish and scorpionfish, but hands should be kept away from mouths and venomous spines.

Minimum aquarium size is 500 L, with 700 L or larger recommended for long-term care. Maintain temperature at 24–27°C, pH 8.1–8.4 and salinity 1.024–1.026. Provide strong biological filtration, quality protein skimming and regular water changes of 10–20% as required to control nitrate and phosphate. Flow should provide good oxygenation without preventing the fish from resting. Lighting can match the system and is usually not critical for the fish itself. Aquascaping must be stable, with secure rockwork that cannot collapse if a triggerfish, eel or large predator pushes through it. Eels require a tight lid with no gaps.

Breeding is not normally achieved in home aquariums. Spawning involves pelagic egg masses and specialised larval development. In home aquariums, breeding should not be expected. Many of these species have complex courtship, pelagic eggs or larvae, large adult size or specialist rearing needs. The practical focus should be correct feeding, stable water quality, secure housing and careful tank mate selection.

Suitable tank mates may include larger tangs, rabbitfish, robust wrasse, large angelfish with caution, larger clownfish, suitable triggers, groupers, larger hawkfish and other predator-safe marine fish. Match tank mates by adult size, temperament, feeding speed and risk of being swallowed or bitten.

Avoid small gobies, small cardinalfish, tiny wrasse, ornamental shrimp, crabs you want to keep safe, delicate timid fish, slow feeding fish, very aggressive tank mates in undersized aquariums, and any fish small enough to fit into the predator's mouth. Avoid open-top tanks for eels and avoid casual handling of lionfish or scorpionfish due to venomous spines.

Is your tank ready?

A few quick checks before you buy save most of the common losses.

Tank size for the adult, not the juvenile

Check the species page for max size and minimum tank size, and size your tank for what this animal will grow into — not what it looks like today.

Cycle first

Your tank needs an established nitrogen cycle before livestock goes in. Adding fish to an uncycled tank is one of the most common causes of early losses.

Match the conditions

Check temperature and pH on the species page against what your tank currently runs, and make sure you've got the right gear — a heater for tropical species, adequate filtration turnover, lighting and CO2 for planted tanks, or the right salinity setup for marine.

Start conservative

New to the hobby? Start with a small number of hardy species and add slowly — overstocking a new tank is one of the fastest ways to crash your water quality.

Where we ship

We are based in Brisbane and ship live fish and corals to most of Australia. Some states have import rules that may affect what we can send and the cost.

• Western Australia: Import requirements and fees may apply. Read first.
• Tasmania: Import requirements and fees may apply. Read first.
• Northern Territory: May require a permit and be subject to quarantine.
• Regional and remote areas: Carrier options can be limited, which may affect service and transit time.

If you are unsure we can reach your location, please contact us before ordering.

A note on timing: All transit times are estimates and can vary with your location, the weather, and carrier schedules. Regional and remote areas may take longer. To give your livestock the safest trip, please order early in the week.

Live Fish

• Oxygen-filled bags — each fish is bagged in clean water from its own system with a generous charge of pure oxygen, giving many hours of safe transit time.
• Double or triple bagging — spiny or sharp-finned species (catfish, plecos, marine oddballs) are multi-bagged with liners so a spine can't cause a leak.
• Dark, calm transit — bags are packed upright in the dark, which keeps fish calm and lowers their oxygen use during the trip.

Live Corals & Inverts

• Individually bagged or cupped — each coral travels in its own bag or rigid cup of system water, sized so the piece can't knock against the sides.
• Frags secured — frag plugs are held so they can't tumble or land face-down against the polyps.
• Inverts packed to species — shrimp, snails, starfish and anemones each get the packing method that suits them, not a one-size-fits-all bag.

Live Plants & Tissue Cultures

• Moist, not swimming — plants travel wrapped in damp paper inside sealed bags, which prevents both drying out and rot in transit.
• Tissue culture cups sealed — cultures stay in their sterile cups, cushioned so lids can't pop.

The Box

• Insulated foam boxes — all livestock ships in polystyrene-lined cartons to hold temperature steady.
• Heat or cool packs by season — we add heat packs in winter and cool packs in summer heat waves, based on the forecast for your delivery route.
• Void fill and bracing — bags are braced so nothing shifts, even if the box travels on its side.

When Your Box Arrives

Open the box promptly, check everyone in, and follow our Acclimation Guide before releasing anything into your tank. If something has gone wrong in transit, take photos of the unopened bags straight away and see our Live Fish Arrival Guarantee for what to do next.

Dead on Arrival (DOA) Cover

DOA cover applies only to livestock shipped by air freight. It gives you peace of mind that eligible animals are covered if they arrive deceased. Full terms are in our Live Fish Arrive Guarantee.

How to make a claim

• Take clear photos or video of the deceased livestock in the sealed, unopened inner bag.
• If double bagged, you may remove the outer bag, but the inner bag must stay sealed.
• Take individual photos or video of each animal once unbagged, where applicable.
• Send your claim by email or text message within 4 hours of receiving your order. Claims by Facebook Messenger or phone cannot be accepted, and claims made after 4 hours may be declined.
• Please include: your name, order number, approximate time received, number of bags affected, and quantity of livestock affected.

If your claim is approved

We will offer store credit or a replacement of the same item, subject to availability. Replacement shipping is covered only if more than 50 percent of your order arrives DOA. Shipping charges and fees are non-refundable.

To keep your cover valid

Be present at the airport or at home to receive your order, and collect it promptly. Livestock left unattended, returned to a depot, or delayed in collection may void cover. We can only ship to a valid residential or business address, not PO boxes or third-party addresses.

Why quarantine

Quarantining new arrivals before they go into your main tank protects the fish you already have from disease, and gives new stock time to settle and start feeding under close observation.

Freshwater Fish

• Duration: 2 to 4 weeks in a bare-bottom tank with a cycled sponge filter.
• Watch for: white spots, flicking or scratching, laboured breathing, clamped fins, and loss of appetite, checked twice daily.
• Medication: only if a problem appears — quarantine is for observation, not routine treatment.

Marine Fish

• Duration: around 4 weeks minimum.
• Options: observation only, a copper treatment held at 2.0 to 2.5 ppm for at least 30 days, or the Tank Transfer Method (four transfers over about 12 days).
• Flukes and worms: treated with praziquantel, with a repeat dose about a week after the first.

Before you start

Test your aquarium water, gather a clean bucket and net, and dim the room lights. Never pour transport bag water into your aquarium — always net your livestock out and discard the bag water, since acclimating too quickly after CO2 build-up in the bag can make trapped ammonia rapidly more toxic.

Freshwater Fish

Float the sealed bag for about 15 minutes to match temperature, then open it into a bucket and add roughly a cup of aquarium water every 5 minutes for about 45 minutes. Net the fish into the tank, keep the lights off for the rest of the day, and hold off feeding until the next day.

Marine Fish

Use the same cup method as freshwater fish, but keep the lights off or dimmed for at least 12 hours after introduction, and hold off feeding until the next day. We recommend quarantining marine fish before adding them to your display.

Corals, Clams & Invertebrates

• Drip acclimation is recommended: 1 to 2 drops per second until the bucket volume has at least doubled, around 45 minutes for fish-safe inverts and 60 to 90 minutes for corals and clams. Echinoderms such as starfish, urchins and sea cucumbers need the slowest acclimation of all.
• Handle corals and clams by their base, skeleton or frag plug only — never the soft tissue, polyps or mantle.
• Light acclimation: place new corals low in the tank away from strong light and flow for the first few days, then raise them gradually over 1 to 2 weeks.

Full details: see our Acclimation Guide for the complete drip and cup methods and coral dipping.
