Thanks for your input, guys. I may end up keeping one red crab instead of fiddler. Those seem to not require brackish water? I'll also be throwing in some rcs.
Still a bit undecided on plants but am currently considering:
- fissiden on the wood
- rotala r on in the background
- marimo moss ball
I will definitely take out some of the substrate.
I found a dumpster near my apt that is housing a lot of broken up stones from an apt that is getting renovated (you gotta love manhattan). There are tons of broken up marbled-like stones that may look great in the tank. So I may swap out the piece of wood for a nice slab of stone for a poor-man's iwagami tank.
