Thanks all! Yes, I plan to remove the vast majority of the microswords in the foreground to make space for dwarf hairgrass. I'd keep some microswords on both sides of the driftwood. I can get more small pieces of driftwood, but i wouldnt know where to put them. Pile them up? Spread them out?
I also noticed Im starting to get a film/ stagnancy of the water surface. The fish (otto, gourami x2, guppy fry) are not distressed at all, probably bc they are able to deal with low O2 (labyrinth), but I'll have to keep an eye on it.
