Why Is My Bearded Dragon Growing Slowly?

Many times, dragon owners complain that their bearded dragon is not growing, or growing at a very slow rate. There are a few factors that can cause a hindrance in the growth rate of bearded dragons. However, these can easily be avoided with proper care.

Why Is My Bearded Dragon Growing Slowly

1. Improper UVB Lighting

Bearded dragons need special UVB types of lighting in their enclosures, with a time switch to maintain the nighttime and daytime cycle simulation. The UVB light bulbs provide an ample amount of light with the correct intensity for basking to the beardies. The light intensity is very important for the health and growth of dragons. Their bones also need UVB light to prevent health diseases, weak bones, and MBD. This is because the light helps the beardies to absorb calcium from their diet.

Improper lighting in the enclosure causes slow growth, stunted growth, loss of appetite, and laziness in beardies. Therefore, make sure the enclosure or tank is illuminated with proper lighting. Also, make sure you have an automatic time switch to have a smooth day and night cycle for the beardie. Change the UVB bulb without any delay if you need to. It is best to replace the bulbs with new ones after 6 months.

2. Unhealthy Diet

Beardies need a high amount of protein when they are in the younger stages of age. Feed them 75% of insects in their diet to prevent them from being protein deficient. The diet during the first three months should be rich in protein and calcium. You should feed the baby dragon three times a day to ensure rapid growth.

If you plan the meal carefully in the initial months of the bearded dragon, your beardie will pick up a fast rate of growth. As the beardie grows older, you should decrease the amount of protein-rich insects and increase the number of vegetables and fruits. However, you should always feed calcium-rich vegetables.

3. Early Brumation

Brumation is a phase of deep sleep and rest for reptiles, just like hibernation in mammals. Beardies minimize their activity during this phase and sleep more without eating much. Brumation is normal in mature bearded dragons and is a sign of good health. However, baby bearded dragons should not go into brumation as this is their period of rapid growth. They eat the most in this period to increase their size. If your dragon is going into brumation earlier, then you must contact your vet and make a plan to rectify your beardie’s behavior.

4. Illness

Like all other living beings, bearded dragons don’t grow well if they are unhealthy. Any disease, sickness, or illness can affect the growth rate of beardies. Try your best to keep your beardie fit and healthy. Feed healthy meals, clean its enclosure, and provide them with enough light and space in the enclosure.

Does Gender Affect The Size of the Bearded Dragons?

While females have a shorter head-to-tail length, although their bodies are wider, and their tails are slimmer. The male bearded dragons have a larger head and so helps the caretakers to distinguish between the male and female bearded dragons.
