Crested gecko · Daily diet

What should I feed a crested gecko?

A complete formulated crested-gecko diet is typical. Use a reviewed plan for suitable insects and supplements.

The right menu must fit the gecko's age and body condition while delivering balanced nutrition safely.

The useful checks

Do this

Use the exact species diet and a reviewed supplement plan.
Remove spoilable food and uneaten insects promptly.
Keep fresh water and monitor crested gecko behavior every day.
Record changes so a reptile veterinarian receives useful evidence.

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.

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.

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.

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.
