🚴‍♂️ WONDERING WHERE THE ARC TEAM WAS THIS WEEKEND? 💙

We swapped our usual aquarium duties for two wheels and hit the road for the MS Gong Ride!

Our team was proud to take part in this incredible fundraiser, supporting a cause that means so much to so many and helping raise vital funds for people living with multiple sclerosis.

We were lucky to ride alongside our good friends and suppliers, Chris and Noriko at Aqua Premium and to come together for a fantastic day of riding, community spirit and making a difference.

A big thank you to everyone involved and to those who supported the cause! 💙

Now, it’s back to what we do best! We’ll be trading our bicycles for fish nets and getting back to serving all your aquarium needs this week. 🐠
