Thanks for the info! I did trim the roots a bit, and the plants are already sending out new root hairs, so that's good!
This is how the tank is looking with the stem plants and the Anubis attached to the driftwood. Tried to set up the diy co2 with a couple water bottles since I didn't have any 2 liter bottles, but it leaked. Hopefully I'll pick a couple up within a few days. Thanks for reading! As always, constructive feedback always accepted.
