Follow the stories of the brackish creatures and organisms of 'Lumantia' my giant lagoon vivarium, as it becomes a complete ecosystem, complete with mangroves, tidepools, beach, mudflats, and estuary.

1I Released Creatures Into My NEW Giant Lagoon VivariumMy Giant Lagoon Vivarium, Lumantia, is finally ready to be populated by creatures. After cycling the tank for over a month, the brackish habitat is ready to house an ecosystem of aquatic organisms. There is just one problem: an outbreak of diatoms (brown hair algae), marking the "ugly stage" of the lagoon's saltwater cycle period. But I had just the plan and creatures to help clean up the mess. Question is: will they be able to handle the dangers associated with the changing tides?
2I Added Fish into My Giant Lagoon Vivarium (7 Million Subscribers Episode)We hit the big 7 million subscribers mark, a jihe milestone for this channel, so to celebrate I have chosen my top 7 favourite marine fish species to move into my Giant Lagoon Vivarium. The fish were stunning as they integrated into the brackish lagoon ecosystem, but a tragic event was a reminder of the sometimes hard realities of the aquarium fish keeping hobby.
3Simulating Low Tide in My Giant Lagoon VivariumI simulated low tide in my Giant Lagoon Vivarium (Lumantia). But would the newly added marine fish be able to handle the lagoon's drastic decrease in water? Watch as the fish and creatures react to the lagoon transformation of their brackish coastal habitat. The outcome truly surprised me.
