Quarantine & fish care
Healthy fish.Happier aquariums.
At Fish World Aquarium, we believe proper fish care starts well before a sale. We take the time to help our fish settle, monitor their health and feeding responses and provide the care they need.
Our approach
Giving our fish the time and care they deserve.
Every new arrival is given time to settle into our systems. We closely monitor their health, behaviour and feeding responses, providing treatment when necessary.
With multiple systems available, we can move fish when needed and provide appropriate care.
We’re never in a rush to sell fish. We want to see them settled and feeding with confidence before they leave our care.
What we focus on
Observation
We closely monitor our fish for signs of illness, stress and parasites, allowing us to identify concerns and respond when necessary.
Health care
We provide appropriate treatment when needed, recognising that even healthy-looking fish can become unwell.
Feeding response
We work on getting our fish eating well and confidently accepting a variety of suitable foods.
Stable environment
We maintain clean, stable water conditions through regular monitoring and ongoing system maintenance.
Time to settle
We give our fish time to adjust to their new environment rather than rushing them into sale.
Ongoing support
Our care doesn’t end when you leave the store. We’re always happy to answer questions and provide ongoing advice.
Understanding quarantine
Quarantine is more than observation.
Proper quarantine requires separate systems, strict biosecurity procedures and a defined period without introducing new arrivals.
Observing fish or treating them with medication does not automatically mean they’ve completed a proper quarantine process.
Imported fish undergo mandatory quarantine under Australian biosecurity requirements before release. However, this doesn’t guarantee they’re free from every disease or parasite.
At Fish World Aquarium, we believe in being transparent about our approach to fish care and always recommend home quarantine as an additional layer of protection.
Our commitment
Better care for brighter aquariums.
Fish are living animals and even with the best care, illness can occur. What matters is recognising problems, providing appropriate care and helping customers make informed decisions.
We’re committed to doing our best for every fish in our care and supporting you long after you’ve taken them home.
Good to know
Questions we get asked in store.
We currently don’t offer shipping or delivery for livestock. All livestock purchases are made in-store so you can see and choose your livestock before taking it home.
Yes, we recommend quarantining new marine fish before introducing them to your display aquarium. Even healthy-looking fish can carry parasites or disease and quarantine gives you an opportunity to observe them before adding them to your existing livestock.
Yes! We recommend drip acclimating marine fish purchased from our store to help them adjust gradually to differences in water chemistry, particularly salinity.
Our team can explain the process and guide you through safely introducing your new fish to your aquarium.
It’s not unusual for marine fish to take a little time to settle into a new aquarium. We always recommend purchasing fish that are already eating and encourage customers to see them feed before taking them home. Try offering different foods and check for signs of stress, aggression or illness. If your fish continues to refuse food, contact us for advice.
Some territorial behaviour is normal in marine aquariums, but constant chasing, nipping or injuries should be addressed.
Try rearranging the rockwork to break up established territories, adding more hiding spots and ensuring each fish has enough space. If one fish is being constantly bullied, use an acclimation box or separate the fish temporarily to prevent injury.
If aggression continues, the fish may not be compatible and permanent separation may be necessary. Our team can help you find the best solution for your aquarium.
We don’t accept livestock returns or exchanges for change of mind. We encourage customers to carefully consider their choices and speak with our team before purchasing to ensure the livestock is suitable for their aquarium. This also helps us protect the health and wellbeing of our livestock.
We take great care to ensure our fish are healthy, settled and feeding with confidence before they’re sold. We encourage customers to see their fish feeding and discuss their aquarium conditions, tankmates and feeding requirements with us before purchasing.
Unfortunately, fish losses can sometimes occur for a variety of reasons. If you experience a loss, please contact us immediately. If we’re closed, please email us with photos of the fish and details of what happened.
We may recommend bringing in a water sample for testing so we can help investigate the possible cause and provide advice moving forward.
Refunds and replacements are provided where required under Australian Consumer Law.
Yes, we recommend dipping new corals before adding them to your aquarium. Coral dips can help remove or identify unwanted pests, but they don’t protect against everything. Inspecting and quarantining new corals where possible provides an additional level of protection.
Different corals have different lighting and flow requirements. Some prefer strong light and water movement while others need more sheltered conditions. If you purchase a coral from us, we can help you work out the best placement for it in your aquarium.
No. Some invertebrates may eat corals, other invertebrates or even fish, while others can become unsuitable as they grow. We recommend checking the requirements and compatibility of each species before adding it to your reef.
