Lesson for every one.

I have just lost a naso tang. He has been in my 150g tank 2 months. My kole tang if fine, and eating well. Has been in my tank 6 months. My yellow tank is 4 years old, and is not eating. I fear he will go next. All other smaller fish seem O.K. A few weeks ago I lost my cleaner shrimp after 1.5 years, so I replaced it. Normally all my corals and invertebrates, come from coral only systems at LFS.
The new cleaner shrimp came from a system with mainly fish in it, and I did not Q.T the shrimp.
I can't see any evidence of ich, or velvet. If a fish has velvet, it will eat normally, till it gets infected, and will die quit quickly. Must be some sort of internal parasite.
I can't say 100% it was the cleaner shrimp. I normally Q.T fish, but not corals and invertebrates. Whilst shrimp, or corals can't get fish disease, you can still bring then in to your tank, when adding corals/invertebrates from systems with lots of fish. This hobby is difficult even for a reefer like me, who has been reefing 7 years, and shouldn't take chances.:sad2: So Q.T every thing from fish tanks at LFS, is the lesson I wish to pass on.

Any advice would be helpful, and appreciated. I know quite a lot a lot about velvet, and ich, but little about other fish diseases. I don't want to add any new fish, but is there any advice a fish expert can give me. Many thanks.

I always quarantine inverts for at least some time.
I don't quarantine particularly against ich, but am more concerned with velvet or brook.

Check your water parameters before you blame a parasite. My yellow tang didn't eat for a couple of days and it turns out my nitrates were a bit high. He ate the next day after a big water change.

And yes, I would quarantine inverts for at least six weeks. I learned the hard way last year when what I think was marine velvet hitched it's way in via snails.
