Even clear water can hide a build-up of waste in your substrate.

Fish waste and leftover food sink and rot — affecting your tank over time.

👉 Use a gravel vacuum weekly
👉 Focus on high-waste areas
👉 Don’t rely on filters alone

A clean tank isn’t just what you see.

Do you clean your substrate?

Our stunning Green Phantoms are now ready to go to new homes 🏠
Shipping or collection options available at Coppermillaquatics.co.uk along with many other beautiful fish, plants, shrimps 🦐 and snails 🐌

A graceful bottom dweller that grows to 20cm and is best suited in an established aquarium with good water flow.

They love rooting around the floor looking for food and sheltering in caves or around wood.

Regular water changes are one of the most important things you can do for your tank. Over time, waste, uneaten food, and toxins like ammonia and nitrate build up in the water.

Aim to change around 20% of the water weekly. This helps keep water parameters stable, reduces stress on your fish, and keeps them healthy and active.

Consistency is key — small, regular changes are much better than large, irregular ones 👍

Packed with care — fish welfare always comes first 🐟
Local delivery & free collection available 👍
Nationwide delivery coming soon 👀📦
