I've made some changes. Let me tell you... my tank walls are not clean. I've never really photographed before... I swear it doesn't look this obnoxious in real life, but I'd still like to know how you keep your tank walls so clean. I just have a cruddy brush that just scrunches the muck up together. So... tips there appreciated... particularly along the substrate, where I'm hesitant to clean forcefully. But I also got a used tank, and there's always been some buildup on the outside of the tank (on the left in the last picture) that I just can't clean off. All that aside, some pics.
Wisteria (left side of tank)
Ludwigia (not really sure, see question below)
Jungle Val (back center-right)
Water Sprite (front right)
Mystery other plant
I removed my background in favor of black posterboard as well. DIY CO2 supplies on the way.
So, the guy at the LFS threw in some extra plants that happen to look very similar to my Ludwigia to the point where I don't know which is which. One has a green stem, the other has a red stem... can you tell the difference in the second pic there? Also, I'm not sure what species of Ludwigia it is.
Also, concerning my java fern in the third pic... is it normal to have the brown roots growing like crazy all over? They don't seem as out of control in other people's pictures... can I trim those, or would that harm the plant?
Lastly, I'm debating changing my hardscape... I like my rock arch that I constructed by throwing slabs of slate on the asphault... but it takes up a lot of floor space. I could remove a piece of driftwood as well, or put them both on one side of the tank.
Thoughts? I feel like it's coming along, for all my novice abilities.
