My Giant Cloud Rainforest Vivarium

1. Building the Largest Vivarium I've Ever Made "VIV IV"

I've created the largest vivarium I've ever made, an over 2000 gallon tank which will house an entire biome and ecosystem of flora and fauna. My plan for this massive enclosure is to create a habitat that will connect to my three other vivariums, forming a massive biological space that will help me study how wild ecosystems work - the beginning of a new chapter! But what biome will this new vivarium be?
