Cohabitation
Keeping it singly is the calmest solution for this stress-sensitive species, which is aggressive towards its own kind. In pairs (one male, one female) only works if the pair is compatible – drawback: fighting can flare up at any time, and then they must be separated immediately, so keep a spare enclosure ready. Never keep two males or two females together, nor other day geckos. Rear juveniles individually.

Notes

Very sensitive to keeping mistakes – a humid but well-ventilated terrarium is needed. Magnificently coloured, but not tame to the hand.
