Thank you so much. I see so many people stock their tank with beautiful fish without much consideration for the the fish. I have such a peaceful tank and some shy fish like otocinclus that are very comfortable. I don’t want to bring in fish that are going to stress everyone out. ;-)I have never heard of them to be nippy. It seems like some of the larger body tetras get labeled as nippy but I think for the most part if you have a good sized school,tank and and hiding spots you are safe.
But I think Emperors are a pretty peaceful type of tetra Anyways. I considered them for my tank at one point and never saw anything telling me to stay away
