I got given 3 pepper cory's and some neons today, just as I got in the front door the bag split, I got to the first available tank and put the bag in. While I found another bag the 3 cory's escaped straight into the tank I managed to transfer the neons to another bag and aclimatised them in the tank they were suppose to go in and they are all swimming about happily. The corys however are huddled together under a peice of bogwood and barely moving, they have been there now for a few hours and I am starting to worry. They are in with angels, gourami's, rams, krib and 2 pictus cats. The other fish havent even noticed them, the poor things must be so stressed, is there anything I can do?
Bag Split And Fish Added To Tank Without Being Aclimatised

All I can do is leave a artcle to ph shock.
What was the temp of the tank.
How long was the journey.
Watch out for signs of whitespot, swim bladder and columnaris. if there was a big difference in temp.
Corys are not prone to whitespot though.
pH Shock
As its name suggests this condition occurs when a fish is introduced to quickly into a new environment which has a very different pH from the one it came from, when the pH is adjusted to quickly and the fish have little or no time to adjust themselves, or when the pH is to far outside the fishes normal range.
It is very important that any change in water chemistry is made slowly and fish should never be exposed to changes of pH greater than 0.5 of one unit on the pH scale in either direction.
Avoidance is by far the best solution because in most cases the symptoms don't appear until the second or third day by which time the damage has been done and the fish will probably die.
A fish suffering from this condition will show all the typical signs of shock -
Lying on the bottom and paying little or no attention to its surroundings and ignoring potential threats.
It may even lay on its side or go upside down completely.
There could be other signs to, related to Acidosis and Alkalosis
Excessive mucus production.
Rapid breathing.
Swollen abdomen. (Alkalosis only).
If the condition is allowed to go on for one or two days then the chances of a successful remedy are greatly reduced because a lot of damage will have taken place. If the symptoms are spotted early enough there are a couple of things that will help.
Begin to return the pH to the original pH in steps of 0.4 of one unit on the pH scale and allow 3 hrs in between the adjustments. Make these adjustments until the pH is returned to a safe and satisfactory level.
Treat the tank with a broad spectrum anti-Bacteria/Fungus compound to prevent secondary infections of the Skin and Gills.
Prevention is easy. A successful treatment isn't!

/groups.msn.com/FishHealth/phshock.msnwThanks for the info Wilder, they were only in the bag about 10 mins but were in a plastic tub at the persons house, I dont know how long they were in that. I have kept a close eye on the cory's this evening since I posted. Once everyone else had eaten I added a couple of catfish pellets to where they were hiding. Since they have had a bite to eat they have gone exploring the whole tank, top, bottom all the plants playing in the air bubbles, all looks fine, I will just have to keep my fingers crossed.
Generally hardness is of greater concern than pH due to the differences in osmotic pressure. Generally higher pH water is harder, while lower pH water is softer. Generally drip acclimating is better than the plop method.
Lots of generallys there, huh? Plenty of people have taken fish that are shipped, having to get them out of fouled water, and opened the bag, netted the fish, and plopped them in the tank. Plenty of people advocate doing this, and it seems to work well for them. Locally bred or kept fish get little acclimation in my setup, as long as they have been in tap water from the same supply. Fish from further out, or wild caught get drip acclimated. If the person with the tub of fish is on the same water supply as you are there is little to worry about.
