Sorry for the delay, I only just signed in here.
So happy to hear that he ate & chased down crickets today as well as his eyes being open more.
Were you able to dust the crickets with calcium too?
Since you're using a 20 gallon tank, a High Output T5 bulb would be too close to him on top of the tank. Hopefully you would be able to find the Repti-SUN 10.8 T8 at a petstore. Unfortunately, some don't carry them. A T8 is a bigger diameter bulb than the T5, thought I would mention that. Here's a picture of what you want to look for:
For the hood, I would recommend using a strip light type like this as it will help disperse more UVB rays versus getting the type Walmart would sell but they're not gonna be cheap at a petstore although it will help your beardie out more:
This T8 hood should be placed inside of the tank right alongside along the back wall and pointing down. The placement should allow your beardie to be able to sit on his basking log & get the rays of the UVB as well as the heat of the basking bulb at the same time. The UVB should be within 6 to 8" of your beardie while on his basking log. Hope I explained that clearly enough.
Your little guy in the picture is very far way from the compact UVB so not really getting any rays from it, that would affect his total growth and wouldn't allow for proper absorption of the calcium. I would get a longer branch that he can climb up on, they love to climb.
If you have any other questions, let us know.
