So me and this friend had a massive idea that when we leave school we will make a huge glass Vivariuam, with a huger water section that house shrimps, Koura, Bullies, and other small native fish. Then it would have another huge land section with native plants, ferns, Golden bell frogs, skinks and maybe a gecko? We also wanted to see if this could be a self sustaining thing with only needing the work of water changes, and filter cleaning. IS this possible? Our tank would have to be huge probably over 6x2 metres.
