My giant cloud rainforest vivarium is about to undergo a major change. After a year and a half since its creation, this massive rainforest ecosystem tank, named Pantdora, has developed into something truly biologically spectacular. It contains a complex foodweb of various organisms, including animals, plants, and fungi that have established an ecological balance. But even still, this once dynamic ecosystem has reached a standstill, and I realized a change had to be made in order to solve the issue.
