That would make me wonder if they were truly Pure strain Blue's or more likely a hybrid form. The 45 temps are pretty well documented on the pure strains and range from 45-55 for the majority blue hybrids. True pure strains are pretty rare. I have put Ice in a 10 gallon tank with 30 10 day old fry to lower the temp to 48 and had no morts after 6 hours.
