Sorry to hear you lost a fish.

As to where the infection came from some possibilities are:
- live marine foods
- new live rock (even from fishless tanks)
- new inverts.
- nets siphon tubing, buckets and other hardware used with another marine tank for water changes.
- Hands and arms placed in another tank.

If you only have one tank, some of the above won't apply.
Basically, you can carry diseases into your tank with anything from a marine source that wasn't quarantined.

No. Internally they have a salinity near that of the water and can't osmoregulate like fish.
To a point, marine fish even benefit from hyposalinity because it reduces osmotic potentials and the reduced salt increases the oxygen carrying capacity of the water.

Thanks guys, some of my earlier questions were just to confirm what I thought I knew.

I am really worried. Now the valentini is not eating and is swimming weird. It also has some strange dark colored things on its belly. It is also being more reclusive than normal and it just doesn't seem happy.

I am running out of options. I am slowly bringing the salinity back up to normal so I can administer copper, since hypo doesn't seem to be working fast enough to save my fish.

All my fish are dead.

I'm sorry to hear that DRRT .

So sorry to hear that.

I am sorry to hear that I am having a similar problem in my tank. My ammonia is spiking and I have lost 2 fish in a matter of days. I know how you feel!

Thanks for all your support. This has been a wild month, with a long stream of bad luck and other mishaps. I am going to wait 6-8 weeks before adding a new fish to ensure all traces of the disease are gone. The worst is that in less than 3 months I will be leaving for college thousands of miles away and I will no longer be in control of the tank.

maybe just leave it stocked as is then.. understocked will be easier to maintain for whoever has it whilst you're away...

it's not like you'd see the new fish for long anyway...

Losing fish sucks. Sorry to hear this.
