I've got a 5 gallon hex containing wisteria, anubias var. nana, and bacopa. The anubias, after four months, is finally growing. The bacopa keeps getting uprooted by the platies, so it is not doing well. I bought one bunch of wisteria and now have three bunches of it- once it gets started, it grows very rapidly.
I attached the anubias to the driftwood using fishing line. The others I just stuck in the gravel (regular-sized gravel) with a root tab (fertilizer) for them. I used to add Kent Plant Fertilizer for them but realised that mine do better without it.
I can't seem to upload the picture atm, I'll try again tomorrow.
