Hey guys, so I'm wondering if it'd be possible to add neon tetras to my current tank. Here's the stock 6 Black Skirt Tetras 4 Sunburst Platies 1 Dalmation Molly 1 Angelfish (he's a very little guy, same size as the BSTs right now) I think I read that they aren't big waste producers, and how many should I add if I could add them? Thanks guys!
