Medium Urchin Pods (6 Pack)

Add a touch of the Amazon to your aquascape or terrarium with Castle Dawn Aquatics Urchin Pods, naturally fallen seed pods from the Cochlospermum regium tree. These beautifully textured botanicals are a striking addition to South American blackwater aquariums, creating authentic hiding places for small fish, shrimp, and microfauna.

In aquariums, Urchin Pods gradually release beneficial tannins while encouraging the growth of biofilm, an essential natural food source for shrimp, Plecos, and other bottom-dwelling species. In terrariums and bioactive enclosures, they provide valuable microhabitats for frogs, isopods, and microgeckos, adding both function and visual depth to rainforest-style setups. Their tough, woody outer shell ensures excellent durability in aquatic and humid environments.

Tannins Released: Low to Medium

All our botanicals are organically sourced, free from harmful pesticides, and naturally sun-dried without the use of chemicals.
