I was thinking of converting my tank into a tank with some salt, might do brackish but have not figured how salty I am going to go. This is because I am going to get some mollies and platys and make them the center pieces. I tried this before and the mollies had almost constant ich and so I am going to go ahead and plan the tank with salt from the begging. Right now I have a shoal of about 10 cories, Corydoras aeneus, and I have bred most of them so I am attached to them. I have looked to see how they would react to the salt and I am finding mixed information some saying that they will be ok and others that they are intolerant of salt. My question then is what if any level of salt could I keep in the water and the cories be happy with?
