Is his tail cause for concern?

I got this guy a few days ago, purchased from my job with some health issues (twitching, issues walking, falling over). I noticed his tail has.. Notches? As if it was bitten by one of the other babies he was in with. Maybe a bad shed? He shed pretty much his entire body the second day home.

It looks darker than the rest of his tail, and I honestly didn't notice it when I brought him home so I'm not sure if it's getting darker. He has control over the tip still, it's flexible, and he doesn't mind me touching it. Could it be a break or am I being a worrywart? His other issues have subsided with lots of food and proper lighting, now it's just this that's concerning me. I put arrows to the indentations, I can't get them to show well on camera.

And bonus pic of some cute baby arm waving. He does this every time I handle him. I like how different he is compared to my other beardie when he was a baby. My other male wanted to eat everyone's face at all times at this age. I've never even seen him wave.

Hi there, right now it doesn't look bad but keep an eye on it to be sure there's no band of skin restricting blood flow. You can put a bit of neosporin on or raw honey to keep it from infection. If you use honey be sure there are no loose bugs in the tank.

He's a cutie, nice to hear that you've given him the care he needs.

If the bands aren't open wounds and just look like tighter skin that isn't shedding, you might try some plain aloe to help soften the skin a bit so the bands come loose with the next shed. That may help prevent the end from falling off. If that does happen it's not usually a big deal but infection is the risk as AHBD mentioned and using the honey or plain neosporin on wounded areas will help prevent infection and allow damaged areas to heal over cleanly.

I don't think the blood flow is restricted enough to cause tissue decay. It would probably be black by now, at least at the very tip where it's worst. I've been putting Neosporin on it twice a day. It's a little easier to see the marks in this picture. They're the dark lines that don't quite go with his pattern.

I like him, he's very friendly for such a small baby. I'm used to my grumpy boy. He's napping under my hand as I type this.
