The water is likely unhealthy. Test your water for ammonia and nitrite. If there is anything other than 0, do an immediate 75% water change. If levels are at 0, do a 50% water change today then do daily 25% water changes for the next 10 days. After that do weekly water change of 50% and make sure to do a good gravel vac each week as well. If you do not have access to a test kit, perform the water changes anyway.

Good luck

How big is your tank, how long has it been set up and what fish do you have, OP?
