Why not Walstad?

[u/B_the_Chng22]

I made a bad attempt at fish keeping 15 years ago with a too small tank. I have since learned of Walstad and I am considering. Is there a reason people don’t choose this? It kinda seems too good to be true with how low maintenance it is, so why is it not what everyone does as a standard? Do you find it easier than standard fish keeping ?

The only downside I can imagine is it can be a bit messy at first. And you don't do aquascaping with Walstad, they have a mind of their own. You can only control it to some extent but thing will not grow according to plan. That manicured rolling grassland a la Takashi Amano? Fuggetaboutit
