Ich

Completely disagree. Hypo can and most likely will kill the inverts. I'd leave the inverts in the display and remove all fish to a QT to treat with hypo/refractometer to test or copper with proper copper tests. I'd leave the display fallow for 6-8 weeks.

I get all of my livestock from a wholesaler in LA. To prevent disease, they ship their critters in hyposaline water @ 1.012-1.014. I've never had any inverts arrive dead. For extra measure the fish are also treated with copper.

On a side note, a local marine biologist has done several studies one of which was in regards to inverts hosting ich. He has suggested that crabs and hermits CAN host parasites such as ich in the joints of their appendages. This is why I would also treat the inverts.
 
That is why you should use prevention versus treatment after the fact.

Sure, in a perfect world. Unfortunately it's not an option to everyone.
 
why wouldn't it be an option to everyone? I can't think of any possibilities.
 
Not everyone has the space for a quarantine tank.
 
Hm, my thoughts are if someone doesn't have room for a 10 g tank (heck, smaller depending on the kind of fish, it's not ideal but it can be done in temporary situations), they're either making excuses up or, honestly aren't in a position to have a tank. If someone wants to QT, there can always be found room. Aside from, maybe hoarders.
 
I Just talked to a Marine Bioligist From My LFS and they said Ich is always in the tank. Theres really nothing we can do.
 
So for hypo, do I put the fish in QT filled with water out of main tank and in the course of a couple hours slowly lower the S.G., or does it take a couple days to get them acclimated to it?
