Hi, I need some help. I'm a first time reptile owner. I have a Russian Tortoise in a 40 gallon breeder tank. I'm not sure what type of bulbs/heating would be best for him. I know one side of the tank should be around 95 degrees and the other side around 75 degrees....right? I'm just not sure of what type of bulb I should use, how many watts... If someone out there has any info they could share with me, I'd be very grateful. Thanks!
