The honest fit
Would the adult routine work in your home?
Avoid this
- Do not make one treat or feeder the entire diet.
- Do not combine supplements without checking the instructions.
- Do not copy another reptile species' setup.
- Do not treat a persistent health change as a shopping problem.
01
Build the correct menu
For a crested gecko, build meals around a complete formulated crested-gecko diet, with suitable insects and supplements only under a reviewed plan. Portion food for the gecko in front of you rather than treating treats or one favored feeder as the whole diet.
Follow the formulated-food or supplement instructions carefully. Vitamin and mineral products can be overdosed, so do not stack powders or add extra vitamin D without a reviewed plan.
02
Prepare feeders properly
When feeding insects to a crested gecko, buy captive-bred species, keep them well fed and hydrated, gut-load them before use, and offer prey the gecko can safely take.
Dust immediately before feeding according to the reviewed schedule. Remove uneaten live insects promptly because they can hide, stress, or bite a resting gecko.
03
Use appetite as one data point
Serve fresh food in a clean dish, replace water daily, and wash hands and tools afterward. Keep reptile equipment away from human food-preparation areas.
Track body weight, body condition, droppings, appetite, and activity together. A sudden appetite change with weight loss, weakness, abnormal stool, swelling, or poor temperatures needs more than a different flavor or feeder.
