I love Foo the Flowerhorn ♡ If you want to take on this method be sure to watch a lot of his videos. I feel the narrator does a good job of explaining what works and what doesnt, and why he chooses to change particular aspects. I would not however consider this method "no maintenance" if you watch the dates up in the corner, although the caretaker tends to fast forward through tank changes he does them about once a week. Every week he boils almond leaf water, uses it for a 50% water change, trims the vegetation, and once a month he vacuums the rocks on the bottom and uses a magnetic sponge to clean the inside of the glass. He has tidbits of his process spread out throughout the videos. I've never kept fish, so I am not sure how this method compares to traditional in terms of level of maintenance though.
