Consider Rehoming First
Before purchasing fish, consider contacting an animal rescue or rehoming centre. They may have suitable fish that need a new home.
Rehoming can be a responsible and rewarding option.
Getting the Basics Right
Water Quality
Good water quality is essential for fish health.
You should:
Research how many fish your aquarium can safely support.
Invest in appropriate equipment such as filters and air pumps.
Regularly monitor water parameters.
Tap water must always be treated before being added to an aquarium, as chlorine is harmful to fish.
Get the Right Information
Before buying:
Purchase from someone experienced in keeping fish.
Seek advice from an experienced aquarist.
Consult reputable books, specialist websites and aquarium shops.
If paperwork (such as species details or health records) is not immediately available, obtain written confirmation of when it will be provided.
Transporting Fish Safely
Ensure you have appropriate facilities to transport fish home safely.
Maintain stable water temperature.
Acclimatise fish gradually to their new environment.
Sudden temperature changes can cause stress or illness.
Fish Health
When purchasing fish:
Ensure they appear healthy and free from visible injury or disease.
Observe their behaviour for signs of stress or lethargy.
Fish may require specialist veterinary care if they become ill, which can involve referral to a specialist and may be costly.
Stocking Your Aquarium
Never over-stock your aquarium.
If mixing species:
Ensure they have compatible environmental requirements.
Confirm they will not display aggressive behaviour towards each other.
Research species compatibility carefully before introducing new fish.
The Five Freedoms
Fish, like all animals, require basic welfare standards often referred to as the Five Freedoms:
Environment – A suitable living environment
Diet – A suitable and balanced diet
Behaviour – The ability to exhibit normal behaviour
Companionship – Appropriate social interaction
Health – Protection from pain, suffering, injury and disease
Meeting these needs is essential for responsible fish ownership.
