So I have an empty 70g tank I was hoping to put around 50 neon tetras in to act as dither fish. But what else can go in there as large as I can fit in a 70g with out just going crazy and eating the tetras. When trying to do research I put neon tank mates and I just get gouramis and stuff like that is gouramis and that type of fish the only fish that will use neons as dithers? Ideas or experience please? Thankyou
