Help to ID this illness and Treatment suggestion please

[sokubus]

Hi, can anyone help me to ID this parasite, happend overnight. Fish is new in the tank together with the Yellow Tang.
Eating and breathing normally. Also how do I treat this best? Thanks.

It looks like Ich. Normally would recommend a hospital tank and treatment with copper, then leaving your main tank without fish for 60-76 days. Coppersafe dosed to 2.5 ppm (make sure which type of copper you are using - follow the instructions. If you haven't done a quarantine protocol you could dose prazipro after the copper dosing is over. The protocol for QT/treatment is in a sticky note at the top of the forum. PS - ALL of the fish in the tank will need treatment not just the tangs (in case there are more fish)

Thanks a lot! So it is not Marine velvet you think as this was my guess??? Fish is still eating like crazy and not any other behaviour issues. No power head swimming and no scratching. Don't have a QT tank so have to order one in. Hope he will make it another day or two. Would you treat all other fish immediately as well or wait for symptoms? Don't have to treat shrimps correct?

I would say treat them all immediately. IF there are no invertebrates in your tank you could also do a hyposalinity protocol (and avoid copper) there is also a sticky for that on the top of the forum

I thought Ich because it looks like ich, and velvet usually has breathing problems early. My guess is that this didn't happen 'overnight' but rather it can be harder to notice early on

It’s unlikely to be velvet - as said it will cause rapid breathing and you are unlikely to even notice white spots by the time the fish dies.
All inverts can remain in the tank while fish are in qt.

Just to confirm what the other Fish Medics said - this looks like a classic case of marine ich, Cryptocaryon irritans. It isn't velvet.

FYI - I meant to mention - you can use a brute food safe container as a 'QT Tank' - just a heater and sponge filter - and an ammonia alert badge. I tend to use fritz bacteria in the tank when I put the sponge filter is
