Curved Brownie Pods
These curved brownie pods are roughly 3 inches in size. They not only look cool but also give your fish and shrimp a natural place to hide. They’re natural decorations that help your aquatic pets feel safe and like they’re in their natural habitat.
Over time, these pods slowly release helpful tannins and other good stuff into the water. That helps keep your tank’s pH balanced, boosts water quality, and grows healthy microbes. In short, they make your aquarium look great and keep your fish and invertebrates happy.

Megan Duncan –
The brownie pods look great in my tank and the shrimp love hiding in them. After a few weeks, the water color turned slightly tea-like, which I like. My fish seem more relaxed now.
Isaac Wallace –
They arrived quickly and fit well in my 10-gallon tank. The fish use them as hiding spots, and the water quality has improved slightly over time.

I was skeptical at first, but the pods look natural and the tannins help stabilize the pH. My shrimp are active and my tank looks more realistic now.
