Before I was ready to run the canister, I had a 300gph water pump running (you can see it on the left side). The suction cups came loose one night and, "rolling hills" on the front of the substrate appeared. I'll get that settled back out.
Yes, more plants. Rob, I'm ready, lemme know when I can swing by. I've also start getting clippings from my other tanks, and have some stuff on order as well. Where I struggle is envisioning anything ahead of time and creating it. I typically find plants I like, get them, and then just find an open spot for them. That's how what you see above came about.
Also, there's several things in there hiding from you. Consider it a scavenger hunt. Stem plants that I had or received that weren't very tall (4-6") that I planted deep to let them root since the substrate is so light, so they're very low to the sub and hiding behind the rocks. You can just see the stellata sticking out of the rockscape on the left (1 stem is visible, there's about 8 total back there). On the back right corner is aromatica below the rocks. In the middle of the right rock formation is something else (I'm horrible with keeping track of names of these things). So, not disagreeing that I need more, but there is more than meets the eye at the moment.
I should've done this already, but need to find some wood to add in. I'll work on that.
