The Caves

A less busy region in comparison, but as equally rich with life as the reefs above it. The caves are a deep network of interconnecting tunnels and caverns that span the length NEO-AQUARIATUM. Entering one cave can very easily bring you to the other side of the planet if you aren't careful!
Within the caves are different pockets that contain vastly different communities and subcultures. If it exists, there's a cave down here somewhere where fish gather to talk about it.
For the more contemplative MECKAFiSH who may prefer a cozier and more innocuous lifestyle, the caves are a winning pick!
