3 fish dead in 2 weeks and it does not look good for the rest

[sitandwatch]

Yup Ammonia is at 0.

And really hoping that its not velet also

I hate to say, but I also agree...it does sound like and look like Marine Velvet. I lost a tankful to it once....sorry...

Sadly, hoping that it isn't velvet isn't going to make it go away. If it looks like velvet and acts like velvet (killing your fish quickly, laboured breathing, etc), I would assume the worst and act quickly and accordingly. Time is probably not on your side with this one.

+1 fishoholic I would believe her just read post on MV it is moving... and I sympathies with her for what she went through.

It looks like velvet and the only thing to treat it with is Copper nothing else works freshwater baths while you QT all fish and then the DT has to remain dark and fallow for 3 months to be rid of it. I would QT each fish separately in 10g tanks then the least affected fish have a better chance of making it with out any stress from other fish the QT also has to remain dark. Ambient light from a room for feeding and remember to feed food that has been soaked with garlic and selcon to help with the fish's metabolism and immune system the copper will most likely affect their livers any tangs or angle fish their stomachs bacteria will be killed so they may not do so well.
I wish you all the best with this as you have to be dedicated to help these fish FW dips every day helps a bit. lower the salinity and raise the temp treat with copper. As posted while I was typing water changes. Thats all I can offer you the way of help, other than if they are not going to make it clove oil will put them down. I would dip them first and find out if they have flukes but that would be the worst case of flukes I have seen in a long time.

Agreed about the FW dips. It wasn't until close to the 2nd week of treatment and I got brave enough to do FW dips that I noticed huge improvements with the fish's ability to breathe better.

Honestly it was the worst thing I ever went through in my life. The saddest day for me was when my when my regal tang was dying and it was like she couldn't take the pain the MV was putting her through any more. She started to swim as hard as she could smashing herself into the glass along the sides of the tank and jumping up and smashing her head on the top of the lid to the QT tank. It literally was like she was trying to kill herself (or at least knock herself out) in order to stop the pain. I cried a lot after watching that and I still cry at the thought of it. Makes me sick that I didn't try to save them sooner

Do yourself a favor and take Kien's offer of help.

Yikes... that is sad. In one of the books I have there is some information on euthanasia for very sick marine fish - The Marine Fish Health and Feeding Handbook. The book is at home, and I am in BC though, so I can't offer any more information right now.

Something to consider though if it ever gets to that point.

I got the book at Chapters online for like $35 or something. Its worth the read for sure.

clove oil will put the fish to sleep for good and it is painless.

It is almost impossible to say whether it is ich or marine velvet from your picture.
When you look at the fish lengthwise do you see tiny salt-like specs on it?
If that is the case it is ich and what you need to do immediately is treat the fish as the infestation is serious.
Here is what you do.
Soak dry food like flakes in garlic extract from a health food store or garlic extreme from a LFS. Dry food because it soaks up the garlic much better.
Feed only garlic soaked food as the idea is to put as much garlic in the fish a fast as possible.
Feed very often, overload the fish with this food for the same reason.
If it is not salt like specs you have marine velvet and follow the advice given in the other posts. IME marine velvet kills quickly from the first signs and I note you say that they are dying over a period of 2 weeks.

I never experience MV so i can't offer any advice plus i think others already give you enough information.

If funding prevent you from setting up QT. I have a 10 gallon QT tank and copper bottle you can borrow. I am sure others will step up and help if you need more QT tank.

Good luck and may I know where did you buy your recent fish?
