i have an angel fish with white spot on its mouth. its getting bigger and bigger everyday. therefore the fish wont even eat. i've tried the 2 doses of whitespot cure and ammonia clean and added a pinch of seasalt for the tank now. still the disease wont go for two days now and its getting larger! my temp are set to 28 deg is pretty high compared to a normal tank temp. should i turn it right up to 32 deg? is it okay to set it 32 deg if i have fish such as angels, neons, guppies, platy and catfish on the tank?
