He is 100% healthy... eats like a champ regularly... no RI. I am in the process of switching to a rack because I am having a super hard time keeping the temps up in my tanks (I have a zoomed UTH + a heat lamp for the warm side) but still the hottest it gets is like in the low 80's... I put a blanket over the top of the screen (aside from where the lamp is) to try and insulate it but it's not really helping that's why I am going to switch to tubs asap! going to the store to buy rats now.
