MY OH brother went to Vietnam & his hotel room had a resident gecko. Lying under the mozzi net he was fascinated to watch it scurry around the ceiling catching bugs. One night it started making a loud 'tuck-tuck' noise, which woke him up. Another gecko had appeared through the window & the resident one wasnt having any. A big fight broke out....on the ceiling. How is it even possible to hang on a ceiling & fight at the same time :-)
They may be cute but I'm told they will bite if they feel stressed & the bite will often go septic.
