You wouldn’t mind giving me a list of those plants you have found that have thrived please if you don’t mind?
I have found Amazon Swords to do well. The green leaf species/varieties; the red leaf do not do well because they require more light, and I haven't had much luck with the artificial varieties (spotted leaves, and such) which tend to last for a few weeks, sometimes a couple months, but not much beyond. My sword plants are all adventitious plants from older parent plants. The pygmy chain swords are daughter plants stretching back to the original plant purchased in the 1990's.
I have floating plants in all my tanks because I consider it mandatory to provide shade for the fish, so obviously that will reduce light reaching the lower level. Water Sprite (Ceratopteris cornuta) is about the best floating plants, and there is Amazon Frogbit and Water Lettuce.
I have had crypts do very well for some time, years actually. Pennywort seems good. Anubias and Java Fern. Java Moss.
A couple of red tiger lotus did quite well for months; I even got a plantlet or two. But rather suddenly these just melted, something happened in that tank that I never could track down.
