Wow.. All of your tanks are so wonderfully decorated! They're all so roomy as well. I want to get my two bettas, Itchy and Scratchy, a large tank to themselves, but I still live in dorms, and I have to move around. Next year, when I get an apartment I'll get them a proper home.
I remodeled my betta's home. I removed the gravel and some of the plants, then put little sprigs in jars of gravel. It will be interesting to see which plants do okay and which don't. It's easier to take care of without the whole bottom being covered with gravel, which I very much enjoy.
Thanks. I think that there are a limited number of plants that will be okay in a jar, even with pruning. I don't know to what degree being a jar affects gas exchange for the roots. I predict that the brazilian pennywort will be juuuuuust fine, since it's not really planted, the tip is just being held in there by a rock. And the grass and microsword look happy. For now? The amazon sword doesn't look like it's going to make it, but it was struggling before I planted it. It's an interesting experiment.
