help my clownfish look like they are dying

[clownhelp]

Hi all,
I need HELP urgently. I'm not a fish expert but while my husband ( who has more knowledge than me) has been at work the clown fish have took a turn for the worst.
One has been acting strange for a few days hiding behind the filter, now today 2 other have been lying at bottom of tank , looking like they have been struggling to breathe and gone pale. They have not been interested in food either
I don't know what to do. I have checked all water levels and salt in water, which have all come back ok .
Any help would be much appreciated ???

Sounds like they are in distress from something. What were the tests and the results that you ran. Has there been any change in water flow or temp of the tank. if you can a picture of the fish could also help.

ammonia is 0 nitrate 0 both of them ph 7.4

Ph is low. U want it between 8.0-8.2

Ph shouldn't be causing this issue at that level. It's slightly low but not enough to kill the fish or cause excessive stress.
These are the tests we should know about.
Salinity
Nitrate
Nitrite
Ammonia
Phosphate
PH
Temp
A few other questions
How old is the tank?
What else is in the tank?
How long have you had the fish?
Did you buy them all at the same time?
Do you add any chemicals to the tank?
What are you feeding them?
