See if it is moving, like a parasite? Could be Ich. I would so a good substrate vac and a 50 % pwc. To make sure the water is good and clean. Do a test to see what the parameters are. If you don't have a test kit, do another 50% pwc in the morning. Make sure the water is in good condition - like less than .25 ammonia, 0 NitrItes, and under 30 NitrAtes. Clean water will give you a good place to start.
