white dust?

[ickmagnet]

Something is not right with my tank.

After 2 years of everything running smoothly, I've had 3 fish die on me in the last month. Two jumped out of the tank and the third (my precious powder blue), just stopped swimming one day.

I've checked the Nitrite, Nitrate, PH, and Ammonia and everything seems fine.

The only thing "wrong" I can think of is that I do have a lot of aiptasia.

I was taking a look ay my fish today and noticed that all of them are covered in a pwodery white dust, like they are covered in sand or something. I know what ick looks like and it is definitely not that.

They do appear to be eating fine. Any ideas?

When was the last time you add livestock, especially new fish? A few marine fish diseases/parasites have "white dust" as one of the symptoms. Maybe a picture will help. If no pictures, and you are sure its not marine ich, then google "velvet" or "Brooklynella" to see if the symptoms match yours.
Good luck.

Marine velvet

Definitely Marine Velvet. Your gonna have to quarantine your remaining fish and treat them and let the display tank remain fallow(no fish) for at least 6-8 weeks.

Sorry for the late response. It does look like marine velvet. I've been at work and busy setting up a hospital tank as soon as I got home. I maanged to get my puple tang out of there but looks like he won't make it. I'm treatinmg with copper. I'm keeping my fingers crossed.

I'm going to go in there now and try to get the rest out. It's not going to be easy. Not sure how I'm gpoing to fit all my fish into the 10 gallon tank.

Yikes!! What a nightmare. Everything was going so well for the last few years.

sorry to hear that. When you see symptoms for velvet, it's usually too late. A fresh water dip before you put them in the hospital tank might kill off some of parasites on the fish skin.
Good luck.
