Leo tail bump?

[espiomar]

Hello. We recently purchased a leo near xmas time. I am estimating he is about 4 months old now. He has always seemed healthy. Eating is normal and consists of crickets, dubias and mealworms. He poops normally. He is friendly when taken out and played with. He is active. I have never seen any signs of fatigue or sickness in him. His habitat is clay tiles, moss, driftwood, and 3 hides. Temps are checked with a temperature gun and digital sensors and all seems normal and fine.

A few weeks ago, he developed a large bubble/bump on his tail. At first, I thought it was a calcium buildup, so I cut back his calcium from 3x week to 1x week. However, this didn't really help. The bubble/bump hasn't grown or gotten smaller. I am afraid to touch it directly, but I honestly don't think it is bothering him.

Has anyone experienced anything like this before?

Has he ever lost his tail that you know of? It almost looks like one of the 'rings' of his is just growing in wonky. Sometimes when they have had a tail injury or dropped their tail, the new growth does not look quite the same and may be a little abnormal in shape.
The structure of their tails is unique to this genus of lizards and forms as fat is stored there in the concentric rings that give it that look. On your lizard it looks like one of these deposits is just out of sync with the rest of the tail. May not be anything to worry about, but if it gets red, bruised looking, opens up, bleeds, or anything unusual like that, then a vet trip might be in order.

The calcium bubbles are usually under the front legs and sometimes the rear legs, not usually on the tail.

I would agree that it could just be an abnormality and should be watched for what the poster above recommended. I guess it's possible that there could be some sort of benign fatty tumor as well, but it's probably best to just keep an eye on it and check for changes.

Thanks for the input everyone. We dont believe he has ever lost his tail, as when we bought him he was most likely 1-2 months old and had a full fat tail already. Hopefully it is nothing, but we will keep an eye on him and see if it changes.
