My wife picked up 40 bluegill fingerlings and 4 catfish on friday to add to our first setup which we just finished cycling. 9 of them died on the way home, and 5 a day for the next two days. The ph is reading 7, no amonia signs and water temp is 71 degrees. Also, a few fish are showing discolored regions on their back and tailfin.
Is this mortality rate in a stressful move usual? Should I be investigating / worrying about an underlying problem that may kill them all? When I visit them, they seem happy. They are usually grouped on the sunlight side of the tank and eat small coy & goldfish pellets that i'm crushing for them
latest readings: amonia .25 ppm; 7.2ph; 72 degrees; 0 Nitrite; ~80 ppm Nitrate

Looks like some sort of bacterial infection (then again most infections are bacterial.)
Salt is about the only thing I know to do.
Hey Jon and Everyone else,
THe bluegills I bought from you, Jon, are doing pretty good. A few died during the move, but overall they are swiming vigorously and eating like champs. I think the big secret for my system was adding a constant supply of oxygen through a battery powered air bubbler, which I hadn't had before. I bought 4 rechargable D batteries and I just rotate them in every day.
I few days ago, I noticed one fish has developed a white fuzz on one of his fins. Did some quick reading online and it looks like its cotton ball disease?
I have been feeding pretty liberally, using flakes in addition to the grubs and wierd bugs I find in my compost tea. How does over feeding lead to bacteria infections?
I quarentined him today in a separate bucket with a bubbler and some salt. And I salted my system at about 2.5 parts per thousand, mostly because I ran out of salt and I wasnt sure if I was going to shock the whole group of fish. Would you recommend Salting my system the full 5 parts per thousand? For a number of days? or just once.
How would you approach my sick buddy in the bucket, does he have any hope?
update: I have 11/40 bluegills remaining and 4/4 catfish. It has been several weeks since the last fatality. All the remaining fish are in good spirits and showing noticeable growth. I don't want to get ahead of myself, but hopefully these guys have adjusted to the system.
