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

A thriving reef aquarium is about more than just fish. We also stock a fantastic range of healthy marine corals, including colourful soft corals, LPS, SPS and coral frags, with new arrivals throughout the year.

Whether you’re creating your first reef aquarium or adding the finishing touches to an established display, our experienced marine team can help you choose corals that are suitable for your lighting, water parameters and existing livestock.
