I ordered another 12 because I love these guys. This group has all survived and been thriving. Whatever was wrong with them before must have been sorted out. They're through a month of quarantine and now in the main tank!

They die off within a month of receiving. They eat and are active but slowly die off one by one. Out of 24 (spread over several orders), only 2 survived. They were from my original original order of 4. Those 2 are thriving with a group of other sensitive corydoras. I really did everything I could for these guys. I've kept a lot of cories and I'm fairly confident it isn't an issue on my end. I think they might be wild caught and don't acclimate well to tank life.

My first group (4) survived so I ordered 8 more. Out of those 8, 2 made it. It seems like they had some sort of wasting disease. Luckily, treatment (paracleanse) managed to save a few. Highly disappointed in this batch though. 6 cories dying in a week is rough.
