Help with internal growth identification on rummynose tetra

[paul.stopher]

Can anyone help identify what’s wrong. Had the school for about a month and started to notice and internal white/yellow mass growing inside on one of the school.
Does anyone have any ideas as to the cause and treatment.
thanks

@paul.stopher I have no clue what this might be about. Hopefully someone who knows will chime in.
Is it just one individual? Is it otherwise behaving normal in terms eating, swimming, schooling/shoaling ? If you can, especially if the fish starts to show obvious signs of sickness, you might want to isolate it and see how it goes.
Cheers,
Michael
