its just the one big white spotAnushanthh said:fish scratching the tank is a symptom of poor water quality. first of all do a partial water change and check your water parameters.
if still your fish scratching only treat your fish with medication.
tiny white spots all over the body and fins are symptoms of ick. observe your fish closely for the symptoms.
if you feel your fish has ick increase your water temperature slightly and add antiparasitic medicine.
it may be the injury caused by scratching. in case check your tank for any sharp objects that can cause injuries to fish.Lauren Couch said:its just the one big white spot
