Well, the Fireball-type Neo on the top left has grown, and the Neo down and to the right of that one has gotten some nice color. They're not really fast growers. I have better growth with mine when I keep them full of cleanish water, and when they have some sphagnum around their base that is watered daily or so.
Tough to see from the pics, but I'm not seeing any species that are really going to show a lot of growth. Do you have any close up pics of certain plants to illustrate your concerns?
I think I could turn and live with animals, they are so placid and self-contain'd.
