Help!

Happened overnight not sure what it is. Half my fish seem to have it? Any help would be greatly appreciated

Probably need to take a picture without the blue light. More white light. It’s hard to actually tell with all the blue.

One of them is. Also not eating. The other sailing is eating and in the light

if the fire fish is hindding that's normal but do a water change

I know it can be tricky and hard but can you try to get a closer/clearer picture under white light. The clearer the better to help ID

That sailfin tang has severe late stage ich. You’re going to need to move of the fish into a tank with NO invertebrates and treat them with either coppersafe at 2.5 ppm for 30 days or with hyposalinity (low salinity) at a specific gravity of 1.009 for 30 days. If your tank has no inverts in it, you can run hypo right in the tank. Some people, with just a few inverts, find it easier to move those out to a smaller tank.

You’re going to need to get started on this right away because the fish don’t have much time left.

Let me know if you’d like me to walk you through either treatment.
