So i just noticed one of my dragon blood's is hiding and breathing heavy, his/her color is basically white now. They're all about 1.75"-2" right now and in a 40 breeder. Only this one is heavy breathing, and its the smallest of all 11. I noticed something happened with my heater and the temp dropped from 80 to 74, i swapped heaters and now its at about 76. I dont know what could of happen to make the heater just stop working like that, but could the temp change be the reason for this? He/she didnt accept food while the rest did.
