So not good results. They made it 10-11 days in copper. The past 2 days I've lost 4 to bacterial infections. I feel I'm fully responsible. These sensitive fish may require more frequent water changes in qt
They are pretty hardy once they are past the second week or so but for me it was the first few days.
They also hate quarantine.
They are a fish that likes to hide allot if they feel threatened. Make sure you provided them lots of hiding places or they will be stressed in quarantine. Once comfortable they do swim out allot. I think this constant fear is why they shoal so much. They can be skittish.
