Using live insects in terrariums can add an interesting and dynamic element to your setup. Different insects can play various roles within the ecosystem, such as scavenging, pollinating plants, or breaking down organic matter.

Live worms can also be used as a food source for fish kept in aquariums or ponds. Many fish species, especially carnivorous or omnivorous ones, enjoy eating live worms as part of their diet. However, not all types of worms are suitable for feeding fish.
