Lotus Pods are ideal decor for blackwater tanks as well as many other setups, providing shelter to fry and small species of shrimp, crabs, crayfish, snails, and fish while maintaining a natural look in the aquarium. They also serve as an ideal growth medium for biofilm and diatoms, both of which are key food sources to countless aquatic animal species, including shrimp and other invertebrates as well as fish.

Lotus Pods also have buffering qualities. As they decompose, they release tannins (tercatin, punicalin, punicalagin) that lower the pH of the aquarium, but at a gradual rate. This is particularly beneficial for aquatic animals that require acidic, low-pH water. Lotus Pods can also be used sparingly in high-pH setups as well.
