🐠 Fish Tank of the Week 🐠

There’s something so calming about a goldfish tank 🤍🐟
A gorgeous CADE Altumate S2 1200, no fancy decorations, just happy goldfish gliding in pristine water

We love a beautiful setup, where the fish come first before anything else.

Are you a fan of simple goldfish tanks too? 👇

Wondering where our boys have been this past week? 👀👀
Hornsby - Orange 🛻, We go the distance for your dream tank!

This one was a little further from home but that didn't stop the ARC boys from hitting the road, and getting this beautiful Reef S3/P 2200 CADE installed for our customers in Orange!

There nothing better than seeing a tank come together, and knowing it'll be enjoyed for years to come. This is what it's all about for us, seeing a vision come to life and being apart of your journey.

It's our pleasure to go the extra mile (or few hundred kilometres) for our customers!

Big or little, near or far - we love what we do! 🩵
Come chat with us in-store, to get your dream tank!
