aponogeton boivinianus and longiplumulosus will look spectacular in that size tank. Their such a ignored large format plant.
Yah I love them. I have been growing A. longiplumolosus for years. One of my favorites. But this is the first time I was able to get my hands on A. boivinianus. Excited to see how they will look in such a big tank. And hopefully I can get the Crinums going as well. I have had the Crinum natans for years now smooshed into a small tank but it it looking a bit sad now. I hope it will bounce back.
