Great Danio Had White Spot On The Lip

[Jelena]

Hi, everyone ! Can you help me please to find out what is the small white spot on my Great danio's lower lip. It sometimes go away and appears again. Danio is active and eats well . I have danio for about three months and don't see this spot growing. Other fishes are OK . Thank you fir replay.

This could easily be a bit of damage from your (Giant?) Danio picking up food from the tank floor, if your substrate is not the finest sand.
