They were in the colwater section of the aquarium section but the lable had tropical written on it. (the only fish that did have coldwater on the lable was goldfish) plus w.c.m minnows and danios (which i have in a coldwater tank) had tropical on the lable...
These are most definitely Freshwater Tropical Fish, although they are all quite hardy fish I would never dream of keeping them in a coldwater tank. They need to be in a heated tank with proper filtration etc
