Sone bad news. All went in fine, but I have just checked them and some appear to have died, but all other inabitants are fine. I think a large water change and testing will be in order for tomorrow.
A quick update. It has been a compete loss of the new additions. Water has been changed and water quality is good. I can only think that they may have been stressed by the activites of the larger catfish and sd's.
The three remaining barbs from the first pickup as still doing well.
