New issue, please help

[Steve Wallace]

So, I've had no problems with the 9 fish in my tank for some time and all of a sudden, overnight three of my fish seem to have three different issues. I checked the parameters this morning and all seems fine (Nitrate a bit higher than usual, but not above normal). I can typically find stuff online, but the fact that three of these guys have three different issues (at least they appear to be different issues) and the fact that this happened within a 10 hour span is the reason for this post.

Yellow Tang: At first glance the issue appears to be "ICH"
Powder Blue Tang: No idea what it is
Blue Throat Trigger: I don't think it is ICH because the white spots are cloudy and not a perfect circle.

I just fed them and they're all eating fine. I'm about to do a water change just in case.

Here are the pictures. Any feedback would be greatly appreciated

Thanks

I would agree the Yellow appears to have ich. Do the other fish appear to have dusting over them?
If they appear dusted or have a golden sheen it could be velvet. Any other symptoms? How long have you had these fish? Did you QT them?
Looking at the fins on the PBT I would almost think flukes also. First step is going to set up a QT tank because all of your fish will need to be treated with copper. I would catch the PBT or Trigger and do a FW dip to check for flukes. But let’s get some other eyes on this.

I agree and it's likely you also have velvet although I can 100% confirm ich and likely flukes. PBT doesn't have but 24-48 hours left in his state, that includes if you treated right now. I'd do a freshwater dip first and remove all of your fish for treatment in a quarantine.

Source a hanna copper checker, copper power, seachem ammonia badge to check for ammonia, and biospira to dose to prevent ammonia. Sorry for the trouble but powder blues and many fish aren't going to be able to live without proper quarantine and treatment.

Seeing you have 9 fish you will need either a big QT tank or multiple smaller ones.
I would start with dosing copper (copper power) at 1.0 ppm and ramp it up to 1.75 over the next 24 -36 hours for the fish in the worst shape. I would FW dip all fish on their way into QT to buy them some time (helps with flukes and velvet). Once all fish have completed a FW dip and are in copper I would dose General Cure for flukes twice 5-7 days apart. You will need to heavily aerate as multiple meds will deplete O2. Get a Hanna checker to keep the copper steady at 1.75ppm especially since you have a wrasse(they can be sensitive).
Your display will need to be fallow (fishless) for 76 days to eradicate ich.

I would Say there is definitely ich on the trigger and YT and likely flukes present as well.

The PBT has secondary bacterial infections at the entrance sites.

All fish will need to be moved to QT and treated accordingly.

No other fish seem to show symptoms. I have 2 Clowns, Damsel, Wrasse, Gobby.

I will start setting up a Hospital Tank and do a freshwater dip.

I just got these three fish about 1.5 weeks ago and did not quarantine. I did a freshwater dip before they went into the tank. I'm home all day, every day and have been watching these guys like a hawk. Everything seemed fine until this morning, which is why I'm surprised that this happened so quickly (overnight) to all three fish.

I have been feeding them daily and have been adding API General Cure to their food every other day since they've been in the tank.

Unfortunately, this is fairly common. It isn't that the fish haven't had them up until now, it's that they haven't been overwhelmed with them. The 10 days is enough for 3 generations of velvet and 2 generations of ich so the timeline fits.

Remember, you aren't seeing the parasites themselves when it comes to ich and velvet. You are seeing the mucus response of the fish to the parasites. When the immune system of the fish is keeping the parasite in check, it has a very limited mucus response because it isn't needed. Once the adaptive immune systems starts losing the battle the innate immune system goes into overdrive generating mucus. This is why fish go from being asymptomatic to looking covered in a day or 2. They have been fighting it the entire time, this is a sign they are losing the battle.

Unfortunately all fish (not just the new guys) will need treated. The "spots" are actually mucous production at the entrance sites... not the parasite. It's likely started in their gills and you are just now starting to show on their bodies, quite common. The time-frame is about right as well...

Ok everyone... Now I'm really baffled. It has only been about 4 hours since I took pictures this morning and the spots on my PBT are almost completely gone. I haven't done anything other than feed them this morning. I'm still going to put them into the Hospital Tank, but I'm really baffled how the spots on the PBT and Yellow Tang have now almost completely disappeared.

Thoughts?
