Hi and welcome to the forum

Test your water quality for ammonia, nitrite, nitrate & pH. Post the results here. Then do a 75% water change and complete gravel clean.
Make sure any new water is free of chlorine/ chloramine before it is added to the tank.

After you have done that, post a picture of the fish so we can have a look at them.

-----------------
How long has the tank been set up for?
How often do you do water changes and how much do you normally change?
What sort of filter do you have and how often do you clean it and how do you clean it?
