Lovely setup you've got there.
I've noticed a similar issue with my neon tetras - they've developed white growths around their mouths, which I'm concerned might be a viral disease that's been going around in the UK lately.

Lovely tank, by the way. Those neon tetras of yours have some white growths on their mouths, which seems to be a viral disease that's going around in the UK.
