Disease help

[fishoholic]

I think some of them have ich, I'm just wondering if it's not something more then that. I was thinking maybe brookynella but this part "obvious excessive mucous sloughing off of the fish" isn't happening with my fish and what also doesn't make any sense about any of this is that my female ocellaris and my maroon clown seem symptom free, but my male ocellaris (that also didn't have any visible signs of disease) went MIA 2 days ago. Also my skunk clowns who have noticeable salt size spots on them and are breathing a bit heavy are still alive.

My grouper has lost most of his colour and hasn't eaten in 2 weeks and is breathing heavy but still alive and my pink tail trigger who is covered in a dusting of ?ich? is still alive, but my niger trigger who was eating and seemingly symptom free went MIA yesterday and I found my scooter blenny dead yesterday. Scooter also seemed symptom free, examined his dead body and still could not see any signs of disease on him, even checked his gills which looked clear, wondering if the kanaplex did him in, but then my sand sifting star is still alive and seems fine so I don't know.

Wish I knew what was going on for sure
