The "Miracle Of The Fish" Sudoku

** TODAY'S PUZZLE **
Yesterday's puzzle looked impossible and was a masterpiece. Today's puzzle is just a masterpiece. It's by rubenscube, the Dutch mathematician who also designs levels for Super Mario Maker. It's called Aquarium and it's one of the most remarkable sudokus we've ever seen. Give it a try at the link below:

Rules:
Normal sudoku rules apply. Along thermometers, digits must increase from the bulb end. Cells with grey squares must contain even digits. Adjacent digits along a green line must differ by at least 5.
