Urgent need your help about Diamond Watchman Goby

Tonight, I noticed that there are long red lines, about 1mm thick, from the upper lip to the eye area of this little fish. I'm sure this wasn't there yesterday, and they appear on both sides. Does anyone know what's going on? Currently, he can eat and swim as usual. Many thanks if anyone know. I did not find any information in my country but this little fish means a lot to me.

Good luck!

has it changed any with lighting/other stress? Except an injury of some sort - with or without perhaps an infection I cannot think of anything specific. If he is eating, etc - I would watch - I'm sure the others will weight in. I assume other fish are fine? And that there were no additions/and the fish has been in the tank for a while. The total symmetry would go a little against flukes or a parasite - unless there is some kind of infection/irritatiion in its nose.

The left and right sides are asymmetrical (I've added new photos of the left and right sides). Recently, my water change frequency has become very high. Because I added new fish but due to a Brookly outbreak, they died. Additionally, a newly added clown goby died (cause unknown), and this diamond goby had the dead clown goby in its mouth about 10mins. After discovering this, I quickly removed the corpse from the fish tank.And the little fish bit a garlic clove very hard yesterday (about 5mins). These are all the special circumstances happened recently. I have kept this little fish for one year.
