- Cohabitation
- In pairs (one male, one female) is the usual set-up for this small, not very shy day gecko. Keeping it singly is equally appropriate. One male with two females only works in a larger enclosure with several basking and feeding spots – drawback: one female can push the other aside. Never keep two males together.
Notes
Strong green with a continuous black flank stripe. A small range – the European stock comes from a few breeding lines; document the bloodlines.
