anyone hypo a "healthy looking newly bought fish"?

[geaux xman]

anyone bought a fish that appeared healthy, put it in hyposalinity QT, and the fish died?

care to share the story?

i have a 3" bluejaw that was eating very aggressively and appeared very active in a 29g QT(1.020) for 2 weeks. Then i dropped the salinity to 1.009(over 3 days), and now the fish is eating much less and appears near death(very little swimming). This is day 3 at 1.009.

amm 0, nitrite 0, nitrate 0. ph 8.1, temp 77.

I have two 1" green chromis in there too and they appear fine and eating well.

Sorry, I guess I am missing why would you put a perfectly healthy fish in hypo? Some fish will adapt better than others, but fish have evolved to live at 1.0625. It dosn't seem particularly surprising that 3 days at 1.009 is going to effect it. IMO hypo is a last ditch resort if there is a serious problem....

the reasoning is to not introduce ich into the DT tank. i bought the bluejaw from petco. fish can easily carry ich their gills. introduce 10 fish into a DT just b/c it looks healthy without treating is just a disaster waiting to happen. JMO.

from my local board... the guy is from houston.

Another lesson to learn..I didnt QT new fish with copper in a separate tank but added them straight to my main tank so now all my fish have some kind of disease.. All new fish and some old one are dead.

RIP fish:

8'' Achilles tang
lieutenant tang
(2) 11'' Vlaminigi tangs (broke my heart when they die, they were my fish baby, had them when they were 3'') I cant believe 2 small 5'' vlamingi tangs survive
pair of blue throat trigger
mated pair of saddleback clown
pair of false clown
pair of true percula clown
1 cinnamon clown
2 pajama cardinal
18 yellowtail damsels
3 cleaner wrasse

some of his fish....

If the fish is healthy after a month of qt, then they should be fine. No need for hypo, many diseases are stress induced anyway, so, just adding the the problem IMO.

IMO if you are going to QT you need to treat with hypo or copper. QT for observation is a waste of time IMO, you don't know what they are carrying that you can not see.

Are you using a refractometer? Have you calibrated it with a standard solution?

I have QT'd fish purchases before with hypo. the fish all lived through the hypo just fine. The difficulty I have with QT in general is specific fish requirements. Take for example, a goby or wrasse of almost any type. They need a fair amount of sand. Most QTs are bare bottom to keep them clean becuase they're closed systems with limited filtration.

Do you put sand in for specific fish then take it out for other fish?

So, yes, I wanted to hypo every fish I got, but, I talked to the LFS (not petco) about QTing and they indicated that they treat every one of their fish for parasites upon arival. They said they lose more doing this, but, sell healthier fish.

So, I did not QT a goby I bought last night. If he's carrying ich, I just have to maintain a stress free environment for him.... eek.

I did, and still do. It was a blue tang.

I did not QT any of my fish at first. All lokked healthy in the DT, the newest fish was at least 4 weeks old in the tank when it happened. My 3 original tangs all developed Ich. They survived the first attack, only to get a second attack again several weeks later. I decided to upgrade to a larger tank. I transferred all my coral and most of my liverock to the new tank, converted the old tank to a QT/HT, and did hypo on all the fish. All the fish, including the tangs, "looked" healthy again at this point. I decided it was as good a time as any to get a blue tang, so I added the blue tang. He was healthy as can be when he went into the QT at 1.009, and still remains healthy to this day. As do all my fish. No more Ich. I will QT and treat with hypo all future fish, so hopefully, no Ich ever again.
