Marine Velvet in Main Tank!?

[MetaKnight101]

Hi, I am new to reefing and this forum. I recently purchased a Yellow Tang at Petco and made a newbie mistake and not quarantining it.. i know . Is there a possibility that Marine Ich is in my tank? Should I fallow it for 6 weeks or Start from scratch.
- Just a little of a backstory first.
WHen I first introudced my tang he semed fine a couple days later he got white spots. First though it was ich and treated it with Kordon's ich attack in my display tank but realizing it was marine Velvet becasue of the fine sguar looking on his body. I knew something must be done, so I quickly took a 2.5 gallon (I know, i'm sorry this tank is microscopic for a yellow tang but it was so close to dying that I had no other choice, I didn't have any good sized big tanks) I quickly than transferred the Yellow Tang. Does this mean that my main tank is now affected with Marine Velvet? I currently have a cleaning shrimp two Clown fish and a coral beauty angelfish.
None of them seems to have signs of velvet and are eating and look very healthy
Also my friend has also bought a Yellow Tang from the same Petco and same Tank it was in and it was also infected with velvet and died within 9 hours he bought it. I guess thats what you get for buying at Petco..

Can you provide some pics of the fish? IF it is velvet and you introduced it to your DT then yes, your DT will be affected. First list your parameters and take some close ups of the fish so everyone can see exactly what you are dealing with.

While you are gathering your stuff we can get some of the #reefsquad involved. If it is velvet you will need to move quickly because it is very unforgiving.

Parameters of the QT or DT?

Welcome to R2R. Sorry it's for such a bad event that you are here. But lots of good folks to help you. Here's Humblefish's Emergency Velvet Treatment plan. It works: The freshwater dip removes lots of the parasites and buys the fish some time. The Acriflavine has both antibiotic and antiseptic qualities so it helps with infection from the many parasite insertion points. These two steps greatly increase the survival rate. Highly recommend you follow them.
The short version:

• 5 minute freshwater dip

• Immediately afterwards, perform a chemical bath (in saltwater matching SG/temp the fish came from). You have two options:

1. Acriflavine (preferred) - Do the bath for 75-90 minutes, but remove the fish immediately at the first sign of distress. Aerate heavily both before & during the bath, and temperature control the water. The following products contain acriflavine: Acriflavine-MS and Ruby Reef Rally. DO NOT mix acriflavine with any other chemicals.
2. Formalin - Do the bath for 30-60 minutes max, but remove the fish immediately at the first sign of distress. Aerate heavily both before & during the bath, and temperature control the water. The following products contain formalin: Formalin-MS, Quick Cure, Aquarium Solutions Ich-X, Kordon Rid-Ich Plus. Use protection (rubber gloves, face mask, eye protection, etc.) whenever handling formalin as it is a known carcinogen! However, you can add Methylene Blue to the formalin bath (1 capful per 2-3 gallons of bath water.)

• After the bath, place the fish in a QT pre-dosed at 80mg/gal using Chloroquine phosphate. In theory, copper (exs. Cupramine, Coppersafe, Copper Power) should work just as well as CP. However, due to how fast velvet can reproduce you don’t have the luxury of slowly ramping up the copper level as is normally advised. Therefore, the fish needs to be placed in a QT with copper already at minimum therapeutic levels. This is the advantage CP has over copper in this particular situation. (note: highly recommend Copper Power. Here's the dosing info ~ Gary

• While in QT, use a wide spectrum antibiotic (exs. Seachem Kanaplex, Furan-2) for the first week to ward off any possible bacterial infections. Secondary bacterial infections are very common in fish with preexisting parasitic infestations such as velvet.
• Keep the fish in CP or copper (at therapeutic levels) for one month. However, you can transfer the fish into a non-medicated holding tank for observation after just two weeks (explained below). DO NOT lower the CP or copper level before transferring.
