Hey, coral beauty used to had a couple strange white spots that was on dorsal fin and side fin, but they went away and @vetteguy53081 thought it might me lymphocystis. Now throughout and still the CB swam strange like he was fighting the current in the tank super hard. But none of the other fish has a problem so I thought it might be from the condition, it would still pick pods off the wall like regular. Until yesterday and today it has been laying in this patch of anthemic in the corner which is a low flow low light spot. And he is breathing okay and looking around just not swimming. Nothing appears to be on its body just laying on the bottom. What should I do? What could it be? Tank parameters are good phosphate level is a little high at 0.5 but they ussaly are 0.15. Already dosed phosphate-e to bring it down, and I have 4 other fish in the tank and they are doing just fine. What should I do???
