What are the water parameters of that tank, Midnight? Tank size? Tankmates?

55g
no tankmates

added salt to the tank last night

i dont check my parameter either but i learned my lesson the hard way.... maybe up the temp a lil and keep it salted

temp is in the 80's and salt is added
hopefully it goes away soon.
