I don't know what possessed me to do this in survival mode instead of creative, but I built a base doubling as an aquarium. It showcases views in two biomes, and all available flora and fauna. Exceptions: I didn't give Crashfish a tank, and I tried to put a rock grub couple into containment to breed, but they disappeared--a bug? if you'll pardon the pun. This took approximately 36 hours to gather all the materials and construct.
