I provide my gecko with Repashy reptile calcium in a shallow dish. I am not new to reptiles but relatively new to geckos. I have had this particular gecko for about three weeks. I had another gecko before him but I found him a new home. Anyways so far he stepped in it a couple of times the first week and I thought maybe he was licking it but I wanted to be sure so I evened out the calcium so it looks freshly poured. That way I could tell if he disturbed the dish or not. So far in the last two weeks the dish has not been disturbed. He is only a year old and I think they finish growing at 18 months(he's a giant) so I know how important it is for them to get calcium when they are still growing. How often do they lick up the calcium?
