My girlfriend and I began our saltwater journey in January, and we followed all suggestions..adding live rock and live sand, cycling, adding inverts first, then adding fish. We began with two clown fish, then a yellow tang, then a powder blue tang, then a square back anthia, and six chromis.
In April we bought the Anthia, the PB, and the Chromis. A week after buying, the Anthia showed signs of fin-rot and soon died...A week after that our PB developed a "fuzzy" appearance, what we thought was Ich, but we soon realized was Velvet as within 5 days all of our fish had died, except one Blue/Green Chromis.
Unfortunately, we were set to go out of town until the end of May, and left the one survivor with a fish sitter. We came back at the beginning of June and the Chromis was still alive. A few days later we decided that we would buy three more Chromis to see if the Velvet had died off seeing that the other Chromis was happy and healthy.
It has since been two weeks and we have lost two of the new Chromis along with the survivor Chromis....This time the fish that passed did not show any signs of Ich or Velvet, they looked completely normal, except they showed signs of difficulty breathing before they died.
We test our water every week and have never been outside of safe range. We do a water change every other week, while doing a filter change in the in-between weeks. We also keep the tank at 78 degrees and feed mysis shrimp.

We understand that we are going to need to implement a QT, and are completely willing to do that, but we are not sure where to begin.

Is this still Velvet?
Do we need to fallow the tank? (We have snails, hermits, a conch, a cleaner shrimp, and an anemone)
Should we completely empty the tank and clean the rock and sand?
Could we fill the tank with RO and let the pests in the rock and sand die?

Any help/suggestions would be greatly appreciated!!

Thank you
 
Chromis are well known for "picking off" fish until just one remains.
They have a habit of picking on the weakest member of the group.

I did not know that! Our local fish guy told us that they had a peaceful temperament, but it does make sense now that I think about it because they were not schooling like we were told they would. Do you think it is possible that because there were only Chromis in the tank, it wasn't Velvet or any other parasite killing them, but each other?
 
Chromis are well known to killing each other. And Welcome to R2R!!!
 
If you had velvet in the tank and fish have remained in the tank you still have velvet in your tank.

You will need to remove the fish for at least six weeks and go fallow to erradicate velvet. You can leave all coral/rock/inverts in the tank, just no fish.

The fish will also need treated with copper or CP in order to rid them of velvet.

Sorry - the way I first read this is that your girlfriend and you had velvet..... That would be a different question

Now to the rest:

Its hard to keep Chromis together with or without velvet possibilities (like keeping 5 discus in a freshwater tank - the weakest one dies - until the next weakest one dies, etc). So its hard to say. It sounds like you are doing a great job of husbandry with your procedures.

If you think the Anthia died of fin rot - thats not velvet. If it could have been velvet thats a different issue.

Bottom line there is no way to know whether your new Chromis died of their own disease or a disease they caught from your tank. My guess is that the conventional wisdom would be to take all the fish out - and fallow the tank (treating the fish with whatever the conventional wisdom recommends - ie copper or CP).

the invertebrates will be fine in the fallow period - you won't treat them with xxxxxx.

I wouldn't fill the tank with RO...

Thank you for the input! We knew we were probably going to need to fallow, but we were hoping there might be another option.
 
I had 5 Chromis..then 4..3..tried to save #2 by catching my killer Chromis. He got #2 before I caught him. Killer went back to the LFSo_O

My tank got hit by Velvet last year. There is a lot of great info at the top of the Fish Disease Treatment forum. The articles are definitely worth the read!

Welcome to R2R. Your at the right place for anything “salty”.

I think this may be the wrong forum if my girlfriend and I had velvet...lol

We were not aware that Chromis were difficult to keep together...but you learn something new everyday in this hobby!

Thank you for your input!

Welcome to R2R. Your at the right place for anything “salty”.

Sounds like what we’ve been going through the past two weeks! The numbers kept dropping, but one Chromis prevails.
Thank you for the referral to the articles! I’ve read quite a few so I thought I’d join the R2R community and get some input on my specific case! But I will definitely go through the Disease forum!
