Some sad news for Aquarium Co-Op Fans -

We have left the Retail Partner Program. The program requirements were not a good fit for us at this time.

This means we will not be able to restock Co-Op products unless or until we rejoin the program (which we may do!)

So, while we sell the remaining Aquarium Co-Op brand products we will price match their web price upon request.

At time of writing we still have Easy Green (the smaller size), Easy Root Tabs, all sizes of sponge filters, Magic Small Fish Food, Magic Nuggets and more!

This variation on the classic harlequin rasbora is stunning 😍

Same easy care and temperament, just a slightly different color.

I will be a little late getting to the shop this morning, but it was for a good reason! I grabbed more big dwarf water lettuce and a whole bunch of young vampire crabs from home.

Japanese rice fish do not get enough love, In my opinion. They are small, peaceful and often sparkly!

They so really well in seasonal mini ponds. Here in Minnesota, you’ll need to bring them inside for the winter. But they do great for the late spring, summer, and early fall!
