I am stocking my 20 tall with mostly nano fish. The maion goal is to have scarlet badiss, cherry shrimp, and crocodile toothpicks. I also will be adding ottos and black kuhli loaches. What could I add that would swim out in the open kind of like a shoaling fish but wouldnt pester or outcompete my scarlet for food? I want something that is not red. Any suggestions?
