Cohabitation
Pair (1.1). Two males do not work together — they fight over territory and basking spots until one is seriously injured or sits permanently in a corner. One male with several females is only possible in a large, richly structured enclosure, but: females also compete for the best basking spots, and a subordinate animal then eats less — observe and separate if necessary. Several basking and hiding spots are important so subordinate animals can get out of the way, and feed separately as soon as the animals differ in size.

Notes

A subspecies of the lesser Comoro day gecko found only on Mayotte. One of the smallest day geckos of all — needs correspondingly fine food. The two-month cooler phase is a fixed part of this subspecies' annual cycle, not just a breeding trigger.
