I have plans to rescape my 55 gal to prepare for my new addition, the Vieja Argentio ;D I plan to get more driftwoods and rocks. Maybe changing the substrate from plant soil to sand. Is sand okay with Viejas? And rocks... I was thinking river rocks. They're fine right? Need some more advice and opinions. Thanks to everyone in advance P.S I attached a photo of my plan. Did it with paint like how some members do theirs. Sorry if it's not specific, I'm not very good at art. The red circles are where the driftwoods will be placed or plan to be placed, blue circles are the rocks.
