Why did I hear something like this from Toaster: keep your gecko on sand! If it licks the sand you are not keeping it properly!
Like, seriously? Also, leos live on limestone rocks in the wild, so a rough tile would probably be the best substrate for them. On a side note, I have had my leo on a UTH since like 2009 with no issues whatsoever.
I did not say that. I said to keep it on a Topsoil/Sand mix. The gecko can lick the dirt safely with the right temperatures. Also, geckos do burrow, so tile is not the absolute best substrate.
