"Anyone have issues mixing different types of Tetras? Mine are all similar: Colombian Blues (6), Glotetras (4 - my daughter demanded glowy fish), and five Serpae. But they literally school together most times and never fight. I never kept Tetras prior to this tank time so I honestly don't have that much long term experience with them, but I have absolutely fallen in love with the species.\n \n\n\n\tEdit - the Glo's school with the Blues. Truly, except for the color, they look identical. Same build, fin shape, everything. The Serpae's kinda stick together but mix with the rest as often as not.\n "
