Is It Safe

It depends on the species of fish in question but generally it should not be too much of an issue providing you have a filter. It should clear within 24 hours. I changed from gravel to sand with the fish in with no problems or loss.

ok thanks there nothing highly rare just common tropical fish, there's 2 internal filters in the tank and a air stone

Should be fine.
