Bigger enclosure? ?

[wolf100]

Hello. My Mt. Koghis leachie has now reached 50 gramm. He is in a 12x12x18 Exo Terra. At how much gramm is he ready for a 18x18x24 enclosure ? At how much gramm can I put him in his final adult enclosure ?

With my leachie, I usually go with how cramped it looks in it's enclosure. I know that they prefer tighter quarters over large enclosures. I think you can go by sight. Does it look too cramped? Is the gecko longer than half of the width or length of the enclosure?
If so, then it may be time to move.
