Fish Supplies

Creating a balanced and healthy aquarium starts with high-quality equipment and care products. Zoar’s Ark offers a complete range of fish supplies to support hobbyists and professionals alike. From filtration and lighting to décor and nutrition, each product is selected to help you maintain clean water, stable temperatures and a stress-free habitat for your fish.

Aquariums and Equipment

Choosing the right aquarium is the foundation of fishkeeping. Whether you keep tropical, marine or cold-water species, our tanks and cabinets are built for durability and visibility. Complete your setup with heaters, filters and pumps to ensure consistent water quality and circulation.

Lighting and Décor

Aquarium lighting does more than illuminate—it supports plant growth and highlights the natural colours of your fish. Pair your lighting with ornaments, rocks and artificial plants to design a stunning display. Creating areas of shelter and open space helps fish feel secure and encourages natural behaviour.

Filtration and Water Quality

Clean, oxygenated water is essential for aquatic life. Zoar’s Ark offers filters, pumps, air stones and testing kits to maintain balance and remove impurities. Water conditioners and treatments make tap water safe while helping to control algae and harmful bacteria.

Food and Feeding

Fish thrive on a varied and balanced diet. Our selection includes flakes, pellets, live and frozen foods for all species. Supplementing with specialised nutrition helps boost colour, vitality and growth. Feeding small amounts regularly supports digestion and keeps tanks cleaner.

Maintenance and Care

Regular maintenance ensures a healthy, thriving aquarium. Cleaning tools, gravel vacuums and magnetic algae removers make upkeep simple. Test water weekly to monitor pH, ammonia and nitrate levels, adjusting with treatments as needed to keep your aquatic environment stable.

Frequently Asked Questions

How often should I feed my fish?

Feed once or twice daily, offering only what your fish can eat within a few minutes to prevent waste and water pollution.

Do I need a heater for my aquarium?

Tropical fish need consistent warmth, so a heater is essential. Cold-water species, like goldfish, generally do not require one.

How often should I clean my fish tank?

Perform partial water changes weekly and deep clean filters and ornaments every few weeks to maintain water quality.

What lighting is best for aquariums?

LED lighting is energy-efficient and enhances the colours of your fish while supporting live plant growth in freshwater tanks.
