Cohabitation
Pair housing or a group with one male is possible. The reason: as with most dwarf geckos in this genus, several males fight over territory and basking spots until one is injured or permanently cornered. Females usually tolerate each other but need their own warm spots and hides; feed separately if sizes differ.

Notes

Tiny — the feeder animals are the real issue: without an ongoing springtail and Drosophila culture it does not work. The enclosure has to be absolutely escape-proof.
