When Do Chinese Water Dragons Grow Fast?

Your dragon will grow the most in the first twelve months of its life. This is when it’s developing strong bones and eating once a day.

Growth starts to slow once they reach eighteen months until they are 24 months.

When Are Chinese Water Dragons Considered Babies, Juveniles and Adults?

  • Babies – Up to 12 months
  • Juveniles – 12 to 18 months
  • Adults – 24 months and over

Are There Any Care Needs for Each Stage?


Babies should be fed daily with 85% of each meal being made up of insects. Juveniles can be fed every second day and adults can be fed every two to three days.


When it comes to enclosure size, bigger is always better, but as a rule of thumb for each food of lizard there should be two square feet of the enclosure.

So, a two foot dragon will need a three foot long by two feet wide by three feet tall enclosure.

By the time they reach four months, you will want to separate the dragons into their own enclosures bearing in mind that they are very territorial.

If you notice any head bobbing, puffing, or tail whipping when you have more than one in an enclosure, it’s time to separate them.

Factors that Impact Growth and Size

  • Diet Provide a healthy and varied diet to reduce the risk of boredom. Your Chinese Water Dragon will enjoy a mixture of insects, worms, small mice, vegetables, greens, and fruits. Ensure baby dragons eat more insects (85% of their diet) to help them grow strong and big.
  • Supplements – Make sure you use a good quality Calcium supplement to reduce the risk of metabolic bone disease, which could negatively impact the growth of your Chinese water dragon.
  • Temperatures Maintaining optimal temperatures helps your dragon digest its food properly, enabling it to absorb the essential vitamins and minerals it needs. If temperatures are too high or too low your dragon may stop eating, which can negatively affect its growth.


It’s important when choosing a baby Chinese water dragon to remember that it can grow up to three feet in total length and live up to fifteen years.

These can be very interactive and entertaining reptilian pets, suitable for all reptile owners. Be prepared for a large lizard before you bring your new pet home.
