Whether you’re building a nano reef or maintaining a full coral system, we’ve got the livestock, products, and guidance you need. Visit Birchwood Aquatic Centre for all your Marine Fish and Coral needs.

Quality Marine Livestock – Quarantined and Carefully Selected
We hand-select our marine stock from reputable UK suppliers and importers, focusing on health, colour, and suitability for home aquariums. Our marine fish are sourced primarily through Tropical Marine Centre (TMC), one of the UK’s most respected marine livestock and aquarium equipment specialists.
Every marine fish, coral, and invertebrate is quarantined and monitored before being added to our retail tanks, giving you peace of mind when you add new life to your system.
Our marine fish range changes regularly, but you’ll normally find a great variety of species that suit different experience levels and tank types:
Popular & Beginner-Friendly Fish
- Clownfish – bright, hardy and ideal for many reef tanks, clownfish are one of the most popular saltwater fish for beginners.
- Damselfish & Chromis – colourful schooling fish that add movement to community tanks.
- Firefish & Gobies – peaceful, quirky species that do well in nano and small-tank systems.
Mid to Advanced Marine Fish
- Tangs & Wrasses – active swimmers with striking colouration (best in larger tanks).
- Royal Grammas & Hawkfish – beautiful display fish with interesting personalities.
- Dottybacks – vibrant and bold, great for mixed species setups.
Corals & Reef-Building Essentials
Elevate your marine tank into a thriving reef ecosystem with our curated selection of live corals and reef-building materials. Whether you’re just dipping your toes into reef keeping or creating an advanced display tank, we offer a wide range of beginner-friendly soft corals (such as zoanthids and leathers), as well as more advanced LPS and SPS specimens.
Complement your livestock with reef-safe substrates, live rock, and structure-building media—perfect for coral placement, growth, and durability. Our team is always on hand to guide you in selecting the right coral types, placement strategies, and support materials tailored to your tank size, lighting, and water flow needs.
