Bell cups serve as multifunctional bioactive elements for naturalistic terrariums. They provide essential hiding and foraging grounds for isopods and springtails while offering shelter for small reptiles and amphibians like dart frogs. As they gradually decompose, they enrich substrate with nutrients, promoting a self-sustaining ecosystem. Select varieties retain water for hydration stations. Mount to backgrounds or pot live plants within them for dynamic, functional décor that encourages natural behaviors—burrowing, exploring, and feeding—while maintaining aesthetic appeal in bioactive setups.
