I woke up to my clownfish looking like this this morning. She’s been acting a little weird all week, staying close to only one corner of the tank but was still eating.
My parameters are all normal (see below)
Salinity - 1.026 SG
Alkalinity - 270 ppm
Nitrite - 0ppb
Ammonia - 0ppm
Phosphate - 0.02 ppm
Nitrate - 10.2
PH -8.3
Calcium - 440 ppm
Temp - 26 degrees Celsius
It doesn’t look like ich or velvet to me so I’m really struggling to work out what’s happened and if I should be worried about the other two fish in the tank.
I’ve just took him out and put him in a separate QT that I have set up for emergencies.
Please can someone help me work it out?
