Amazing set-up Tim! You have any critters living on the "land" part?
Here's my 20 gallon. Sort of my first attempt at plants. Set up for about 2 months now and the ferns and moss are growing like crazy. The moss have about tripled in size from when I bought it and the ferns are throwing off tons of shoots/roots. 15 watt Coralife bulb and pool filter sand substrate. 6 dwarf neon rainbows, 1 SAE (will be moving him to my bigger tank in the future) and 6 celestial pearl danios.
