You want the cool side around 80'ish---- if hes over a year old he only needs insects 2-3 times per week w/ one time a week w/ the D3 - the other days 2-3 w/ out--- make sure your T5 is directly over the basking decor piece 12-15 inches ---I brought him home June 5th. I can't say I noticed it at all until a few days before my original post, July 7th maybe? He had a noticeable growth spurt and the eye thing came with it. He's in his new enclosure with new arcadia UVB and stronger heat bulb. New basking spot averages 108F. But with the larger enclosure, the far end is only 80. It's only a 48x 18x 18, but it's glass and doesn't seem to like to hold the heat on the cool side.
I use all rep-cal brand supplements. I dust calcium with D3 phos-free on M,W,F, plain calcium no phos no d3 on Tu,Th, and their herptivite multivitamin St,Sn.
Still active and agile. Change in appetite this week, eating more salads, but still munching on dubias. Never shown a black beard once, but does headbob at self if he catches his reflection.
