Reply With QuoteChris, is the QT running all the while or is it just setup? Is the filter seasoned? If it is just setup for the purpose, I suspect the NO2 kit...but that is my opinion only.
tank parameters:
Nh3/Nh4=0
KH=2
NO2=0
PH=7
antichloramine is always used (seachem prime).
------------------
the symptoms tend to be similar for any of my cories that die in quarantine, just trying to get a clue from others.
blood streaked tail area. anal area.
suspect some form of internal bacteria?
3 out of 4 robinaes I bought died this way. the last one survived a qt period of 7 days.

my qt (1ft cube) tank runs all the time.
nh3/nh4/no2 is not a concern at all because I run it with carbon/zeolite and I test the water etc.
reason I use carbon/zeolite mix is so that I don't have to worry about bioload spike/cycling considering that the load of fish I qt changes each week or so.
take note that QT started with the following cories.
2 concolor
2 baby panda
4 robinae
1 tretlii
1 greenline
1 similis
5 baby caudimaculatus
------------------
fish that died - 3 robinae, 1 panda, 1 caudimaculatus.

take note though that the robinae came from a certain fish shop at my house.
so if its a disease what would it be?
the problem with disease identification is selecting the right medication to treat.
yet another problem.
some of the fish . (ie: caudimaculata and guapore only) have very visible red gills.
eg:
Do more water changes to see if it helps...
Plant Physiology by Taiz and Zeiger
the problem with the caudimaculata above is that its only 2 out of 9 that have this problem,same with the guapore
water change regiment is about twice a week.
Stop all medications and do daily water changes...maybe 30-40%...nothing beats a water change. Something is not right...I wonder if all your nitrifying bacteria is still alive? I sure don't like to see those cute fellows die..

Nh3/Nh4=0
KH=2
NO2=0
PH=7
that's my water parameters.
a lot of deaths are species specific (ie: not all corydoras, just one species.)
in my case, robinae, axelrodi are the hardest hit.
go check the nitrite test kit expiration date
red gills are a diagnosis for nitrite poisoning
also, are you using salt?
