To all of our amazing customers,

We want to sincerely thank each and every one of you for your support, business, and friendship throughout the years. It has been our pleasure serving this community, and we are truly grateful for everyone who has shopped with us and shared in our passion.

As many of you may have heard, we will be closing our doors soon. At this time, we do not have an exact closing date, but we will only be open for a limited time before we close for good.

We will be open this Saturday and Sunday from 1:00 PM to 6:00 PM both days.

Everything in the shop must go! This includes:
🐠 Fish
🐟 Tanks
🧰 Equipment
🛒 Supplies and products
…and everything else in the store.

If you’ve been thinking about adding to your collection, upgrading your setup, or just stopping by one last time, now is the time. Once it’s gone, it’s gone.

Thank you again for all of your support over the years. We appreciate every customer who has walked through our doors, and we hope to see you this weekend.

With gratitude,
JJ Aquarium
