Can you post a few more details about your tank?
Things like:
#1 How long has the tank been set up?
#2 How long have you had the fish?
#3 How recently have you added to your tank? (This includes ornaments, driftwood, plants etc)
#4 Did you quarantine the last fish to go into the tank? If so, for how long was it in qt?
#5 What is your water change schedule? How often do you do water changes, and how much do you change each time?
#6 What do you add when doing water changes? Prime? Salt? Stress coat? Anything you add with water changes, be sure to post.
#7 What is your tank reading currently for ammonia, nitrIte, nitrAte and pH? Also kh and GH if you know what they're at, and the tanks temperature.
#8 How big is the tank in question?
#9 How many fish are in it, and how big are they?
#10 What kind of filter/s do you have running on the tank?
#11 How long have the bumps been on your fish?
Add anything else you think might help people to help you, the more you can tell us about your tank, the more help you'll get.
