HB Arowana Bumb on the Side

[Exidion]

Hey everyone,

i just now noticed that my Premium High back asian arowana (1 year old) god a bumb on his side below the scales, it is not that big maybe fingertip big but ofc i am really scared now.
Is there someone with experience with those kind of things? And how or what i can do now? I really dont wanna loose him. He is still so young and he grew up fine until now, he is eating and is all arround fine otherwhise. No health issues or such.

this is my first post here so i am sorry if i forgot to mention something you need to know. Just let ME know if you need anything else from me to be able to help me.

Thanks a lot for your help and your time in advance

since i made the Post ( on the same day i saw it ) .... it seems same or smaller size im not 100% sure tho, and no there is nothing else to see. The scales are normal arround the spot , on the spot and on the whole fish. The scales are not sticking out or something like that. Even with the bumb they lay perfect on the Fish seems so weard maybe it is nothing but with a fish like that i rather watch 10 times then having im dead in de Aquarium.

still the same size and the scales ( or the whole Fish ) look still normal too. Maybe is going away in time when he grows more and stuff
