When buying pond fish, choose a specialist capable of verifying that your pond is suitable for the intended animals. Advice on adult size, population, and water quality is just as important as selecting a specific color or variety.
Aquiflor, in Nodebais, offers pond fish based on the season and availability. Aquishop allows you to browse certain items, such as Sarasas, and prepare your request. Here is how to organize a purchase that takes into account the well-being of the fish and the development of your pond.

Start by describing the pond
Before choosing a species, gather information on the volume, depths, dimensions, and age of your installation. Add the specifications for your filtration, pump, and aeration systems.
Indicate the fish already present, along with their approximate size. Just the number is insufficient: a few large carp do not represent the same load as young fish. Also, consider reproduction and future growth.
If your project is a pond for amphibians and insects, the introduction of fish requires specific reflection. They alter the environment and may consume some of the small fauna. A biodiversity project does not necessarily need to be populated with fish.
Prepare the analysis results
Clear water does not prove that the pond is ready. Analyses provide information on mineralization and compounds resulting from waste. Requirements must be examined for the species considered.
The JBL ProAquaTest CombiSet for ponds includes, among others, pH, KH, GH, ammonium, nitrites, and phosphates. It does not measure dissolved oxygen or nitrates. Additional tests may be necessary.
Aquiflor offers a free water analysis in-store. Ask for sampling instructions before coming and bring information about your pond. The results will be more useful when accompanied by this context.
Choose a species for its adult life
A fish's small size at the time of purchase can hide its future needs. Ask about its adult size, behavior, group requirements, and compatibility with other inhabitants.
Pond goldfish, koi, and sturgeons are not interchangeable. Koi require an installation adapted to their growth and their filtration load. Sturgeons, in particular, have high oxygen requirements and specific dietary needs.
Do not choose a fish primarily because it is presented as a "cleaner." Every animal also produces waste. The population must correspond to a sustainable maintenance plan, with sufficient space and equipment.
Examine Sarasas on Aquishop

The Sarasa — pond fish product page allows you to view several size classes. It serves as a starting point to clarify your request and then verify compatibility with your pond.
Before ordering, confirm the available size, the desired number, and the delivery arrangements. A stock photograph does not necessarily mean you are buying the exact individual visible in the image.
The product page announces delivery by Aquiflor in Belgium. Have the conditions for your destination and the scheduled date confirmed. The transport of live fish must be organized as such; it cannot be inferred from standard equipment shipping terms.
What an exchange with the seller should provide you
The seller should be able to help you verify the suitability between the species and the pond. Prepare concrete questions about needs, feeding, and monitoring after arrival.
- What size and behavior should be expected at adulthood?
- Does this species need to live in a group?
- Is the current filtration suitable for the planned population?
- What observations and measurements should be taken after introduction?
- How should transport and acclimatization be organized in my case?
- What follow-up should I request if a problem arises?
Also specify the pond's health history. A recent disease or unexplained mortality must be examined before considering new fish.
Observe the animals before purchase
In the store, take the time to look at the entire group. Normal swimming, regular breathing, and the absence of visible lesions are useful indicators, without constituting an absolute guarantee of health.
Clamped fins, repeated rubbing, spots, or wounds deserve an explanation. If fish appear sick in a tank, do not simply choose an individual that seems to be doing better.
Ask how shipments are handled and what precautions are recommended for your home. Any potential quarantine protocol must have suitable equipment; an improvised container without filtration or monitoring can create other difficulties.
Prepare the environment before the journey
The pond or receiving installation must be ready before departure. Check your equipment and have the seller's instructions on hand. Avoid performing a complete filtration change and introducing a new population on the same day.
Aquipond NitriBoost can be considered to support biological filtration in situations outlined in its product sheet. Its use does not automatically make a new pond ready to receive fish: measurements and filter performance remain the deciding factors.
Also, provide suitable food. For goldfish, consult, for example, the Aquifood Pond Fish Food Mix Goldfish, then have the format and ration confirmed based on size and season.
Organize transport and acclimatization
Inform the seller of the estimated travel time so they can prepare suitable packaging. Return home directly and avoid unnecessary stops. Protect the containers from shocks and temperature variations.
Request an acclimatization procedure consistent with the transport, the species, and the water differences. A fixed duration found online does not cover all situations. Do not improvise prolonged mixing in a bag after a long transport.
Upon arrival, follow the received instructions and limit handling. Keep the seller's contact information accessible if you are concerned about the condition of the animals or the packaging.
Introduce gradually and monitor
Increasing the population increases the waste load. Proceed gradually according to the capacity of the installation, following analyses and fish behavior.
Note the arrival date, number, and size of the new inhabitants. Observe their breathing, swimming, and feeding. An unusual change justifies a quick contact; marked distress may require a veterinarian competent in fish.
If the project no longer allows you to keep an animal at adulthood, seek a responsible solution with a specialist. Do not release it into a river or natural body of water.
