Might as well do an update while I'm at it. Growth is good. I've been aggressively trimming the tiger lotus to keep its growth more compact. And the fish is fine
Looks like the ludwigia is getting too much light? Regardless I love the color of the new growth. This ludwigia is amazingly adaptive plant. I transplanted some in my PAR38 bowl and it is a deep red all over with very waxy leaves.
I have purchased a cylinder vase for a walstad bowl but i am still planning what plants to get. Any tips?
As far as plants go you could do like a jungle look land fill em with dwarf sag. With a vase a single tiger lotus would look cool, maybe with some micro swords as an easy carpet? Its going to be hard to trim the bottom of the vase so you may want to stick with stems that you can top.
Here is an update on this bowl. Still going strong and exactly a year old at this point. I trimmed back the ludwigia as it was kinda burning out. I plan to add some s. repens to the foreground tomorrow.
