Dragons need a photo period of 12 hrs on and 12 hrs off ---- that means NO colored lights at all NO sand NO heat mats NO heat rocks -- and NO coils for a UVB ---- all these things I just mentioned are NOT good for your dragon -- PLEASE do not listen to the pet store people -- they have not a clue as to how to take care of dragons and will sell you stuff you do not need --- this is what you need
a Digital probe thermometer --- Stick ons are for ambient use only
Temps for basking need to be 95-100 --- place the probe on the spot he sits for basking 10 min then get the temp --- middle of the tank 90's and cool end of tank in the 80's -- NO lights on at nite dragons like it cool and dark temps should be 65-75---
A bright white basking bulb that keeps temps 105-110
And very important a UVB that is a tube fixture NO COILS --- you need a fixture like a 24" Zoo Med Sunblaster or a Arcadia --- w/a Reptisun 10.0 T 5 bulb ---- this is for a tank that is 40 + gallon -- you can get this on
http://www.pangeareptiles.com the Zoo Med fixture will come w/ a 5.0 bulb that can be used on tanks that are smaller size like a 20-30 gallon tank --- I dont know what size your tank is but if its smaller than the 40 I recommend that fixture --- you will need to upgrade the bulb when you get a bigger tank if this is the case -- let me know what size tank so I can help you - the 5.0 and the 10.0 bulbs have different distances and placement ---
