its ok, but shouldnt ever be bred due to the tail kink. the gecko can live without toes, theyre probally in the stomach of a larger tankmate. you can keep it, and it will be fine, but thats all your decision. ive had animals with spine kinks live for years very happily. of course i do not breed these geckos due to stress, and possibility of genetic defects, but i do think your gecko will do perfectly fine.
