dude i have multuple 7-12 in long slate and river rock pieces from my cichlid tanks under a 65 wat flood so it ranges from like 98 to 110 and they hop around and are actually active around the rocks and the cool is like 70-80 i checked a while ago but its a standard 30 with a light hanging from a 2 by 4, like 6 inches from the basking end of the tank so im saying theres plenty of cool side where they can roam and attempt to eat veggies. One thing i have noticed is that they are both eating some prey items (crix and roaches) when i drop them in around the basking spot they show interest and the leather or the healthy one will allways chase some around. and yes to people who havent read this they are housed together till tom or the end of this week if you guys think it is necesary. but I havent had success feeding them seperatly, GO FIGURE. i dont know if this helps. ill put some pics up tom or later tonight.
