I've been rescaping my 30 gallon long, slowly phasing out the old decor to make room for some aqua and hardscaping. I made a cave with lava rocks I bought at Home Depot, Loctite sealant, and then filled in the cracks with Christmas Moss. My finishing touches will be some branches of Manzanita Wood from the back upper corners down to the middle, like the picture. I ordered some Crypt WendtiI and a Yellow Flame Amazon Sword to top off the plants. I'll post pictures soon so I can gather some opinions.
