My sisters beardi has a bump on its nose it wasn’t original ours. I feel like it’s definitely gotten bigger slowly overtime. Any idea what it could be I can ask my sister and we cna take it to the vet it doesn’t seem to affect it, it eats but it doesn’t have a huge appetite in general it looks like it’s been there for a while it looks apart of the skin it’s pretty firm too
