It looks like the start of ulcers. Make sure the water quality is good and add some salt. Salt might help but it might not.

Add 2 heaped tablespoons of rock salt for every 20 litres of tank water. Keep the salt in the for at least 2 weeks but no longer than 4 weeks.

If you do water changes while using salt, add salt to the new water before adding it to the tank so the salinity (salt level) in the tank remains stable.

The sale won't affect anything in the tank.
