Hi, I am new to geckos and reptiles in general.I just got a leopard gecko on Monday. I currently have tile as my substrate in my 20 gallon. I was wondering do you think repticarpet would be better than tile ? Also since i have got him he has only eaten one meal worm is this normal ? Also i was wondering should i have a dish with calcium in the tank or is dusting his food enough ? I noticed the warm side of the tank at night drops to around 70 f is this an alright temp or do i need a nightglow light to keep the temp up ? sorry for all the questions i appreciate your help.
