I bought a 4 inch fox face from my local pet shop . Not a chain one mom and pops place. They told me that they got it 2 weeks before I bought him. They said they knew the owner really well he had him for a year but now he is worried about the venomous spikes so that's why he brought him in to the pet store... I have had him for 5 days. He eats like a pig,no sign of any diseases. The last 2 days I feel like his color is more pale. He is in a 20 g QT tank that had copper in it before but since I did like 3 water changes with noe adding copper. Should I continue or can I dump him in DT.
