I use to use leaves in my angelfish tank for a bit back when I first set it up. Actually I believe you were the one that suggested the leaves I used in that tank back then, almond leaves or something like that I think they were?
Yessir, I do vaguely recall this.
I was curious what natural leaves people might have experimented with. Are all oaks the same?
Recently realizing that apistos come from leaf-ridden habitats and having moved their tankmates out to another tank, I decided to add some leaves, which is what brought upon this post. I'm trying at the moment with some pin oak leaves, as they were still hanging from a tree, 100% dry, while the rest of last years leaves are buried under the snow at the moment.
