Hi Sauzo! I definitely forgot to mention that my T8 comes with the flexwatt tape for belly heat on one of corners, hence why I asked if I should place the RHP in the middle because I do want him to have a "cool corner/side".
To clear things up, the reason why I have both the flexwatt and the RHP is because the city that I will be moving to soon will have a temp drop of below the 60s if the heater isn't left on during the winter. I wanted to play it safe, so I made sure to purchase a RHP, just in case.
