One Gecko, and Eventually a Colony: Record Accordingly
Most pets arrive as individuals. A mourning gecko arrives as a population in waiting. This tiny, soft-voiced gecko is parthenogenetic — every individual is female, every one can produce fertile eggs without a male, and offspring are essentially clones of their mother. Buy one and you have, in time, a colony. That biology makes its paperwork unusual: the useful record is less a certificate than a founder's file, started at purchase and added to as daughters appear.
Ask the questions below, then keep writing after the seller's answers end — with this species, your own log quickly becomes the main document.
Source, Line and Age From the Seller
Get the breeder or seller's name, contact details, and date of sale, and ask which line or colony your gecko comes from. Because offspring are clones, lines are meaningful in this hobby: keepers track them, value healthy established lines, and can sometimes trace hardiness or pattern tendencies back through a colony. A gecko of known line is easier to rehome responsibly — and mourning gecko keepers do move surplus animals on, so that day may come.
Ask her approximate age or size class, and whether she has already laid eggs. A mature female may arrive with eggs developing, and glued eggs already in a travel container or her old enclosure are a normal discovery, not a surprise to discard. Note whether she was housed in a colony or alone, and how large that colony was; a gecko from a thriving group has usually been feeding under competition, which speaks well of her condition.
Captive-bred status should be stated — these geckos breed so readily in captivity that there is little excuse for undocumented origins.
Feeding Records for a Very Small Hunter
Ask exactly what she eats: the size of fruit flies or micro-crickets she takes, whether she accepts prepared gecko diet, and how often food was offered. Mourning geckos are small enough that prey size is not a detail but the whole question — a record of her taking one food confidently lets you stock cultures before she arrives rather than improvising after.
Record the keeper's supplement routine for dusting prey, and the enclosure style she came from: a planted, misted vivarium is typical, often shared with plants chosen to hold humidity. Note any tank mates of other species she lived with, since some keepers house mourning geckos in mixed planted setups and that history affects disease and stress risk.
Your Colony Log: Eggs, Hatchlings and Escapes
From arrival, log egg discoveries with dates and locations — eggs are glued to surfaces, often inside bamboo or behind bark, and take weeks to hatch, so a dated map of the enclosure saves guesswork. Record each hatchling's appearance date and where it was rehoused, because tiny juveniles need protection from being eaten or outcompeted and from escaping through gaps adults cannot use.
Note colony numbers at intervals, animals rehomed and to whom, and any deaths. In a clonal colony, a sudden die-off or a pattern of weak hatchlings is significant information about the line and the setup, visible only because the log exists.
Photograph your founder on arrival — her pale, mottled pattern and any distinguishing marks start the visual record her clones will be compared against.
A Founder's File That Grows With the Colony
Keep the breeder's line details, feeding history, egg map and colony counts in one file, updated as daughters hatch, and send a copy with any animal you rehome so her new keeper inherits her line's story.
KinsLe's Pet Passport holds that founder record neatly, keeping a mourning gecko's lineage, feeding notes and colony history together in one portable packet however large her family becomes.
