For years, N-Koi has been a trusted destination for high-quality Koi Carp, Butterfly Koi and coldwater species. Today, we are thrilled to announce a major expansion to our lineup: we are now selling tropical fish!

Whether you are maintaining a peaceful indoor community tank or setting up a dynamic aquascape, Neil is applying the exact same high standards of biosecurity, quarantine and fish welfare to our new indoor tropical range.

What You Can Expect from N-Koi Tropicals

• Healthy, Fully Quarantined Livestock: Just like our pond fish, every tropical species is carefully acclimatised and monitored before sale to guarantee robust health.
• A Curated Variety: From popular beginner-friendly community fish to eye-catching centrepiece species, our stock is regularly refreshed.
• Expert Setup Guidance: Indoor aquariums require precise water parameters. Neil is on hand to help you balance your tank’s chemistry, lighting and stocking levels.
