I noticed my hognose snake has a sort of dark blotch on her side. Could it be scale rot or something similar?
Not sure I am buying the reasoning of the pet shop. It is more like the other way around. It all depends on the size of the cage and temp requirements but imagine you have a 600W bulb and you crank it up to get 32C. Now if you measure the inputs and outputs say you use 50% of its capacity. Just for the sake of argument. Now if you add a smaller wattage, the bulb potentially runs on full blast all the time to reach the same temperature. It will also need longer to heat up the same so it potentially gets hotter.Just went to my local pet store, talked to some of the people there, I think the wattage of the bulb was too high. Got a lower wattage bulb, hopefully that will solve the problem
My guess is that its none of those "in line" things that were frequent in a lot of Chinese imports of reptile heat mats...You haven’t actually mentioned what stat you are using. Or is the reason the pet store suggested a smaller one because you don’t even use one ?
