My tank would span the entire length of the east coast. It would have different areas where different ecosystems would occur. There would be one section dedicated to mangroves with fiddler crabs and mudskippers..followed by a section with seagrass bed habitat with seahorses, alligator pipefish and maybe even a few dugongs..next would be the largest section of the tank..the coral reef section..where the rockwork is shaped such that the water gets deeper and deeper..with light demanding sps on the shallower shelves and LPS and soft corals in the deeper regions. Will mix in some deepwater species such as lanternfish and nautilus.. Next section would be the pelagic section where I can house hopefully marlins and swordfishes, dolphins, blue fin tuna, hammerhead sharks... Seawater will all be pumped in from the neighboring sea.. Charge each visitor a $15 entrance fee. And give them the option to buy anything which fits their fancy. And for maintainence of the tank...I shall do it all by myself... Best to die maintaining the love of your life..
