Just finished putting this tank together today. I think the scape looks a bit flat, should probably look out for a nice piece of manzanita to change that. These guys have only been here since Wednesday, but you can already see a tiny glimmer of color. Hopefully once they settle in I can go about figuring what exactly they are. The green rock is covered in a gelatin, powdered algae, and golden pearls mixture, as they are algae eaters in nature. Looks like it's working so far.
