Hi i have a 72 gallon bow tank with Cory cats and rose line sharks, I came to look at them and I noticed the Cory cats seemed stressed and it looks like one has a pimple looking structure on it and the on the rose lines, each of their upper fins seem to be black and also have something on them. Any help is good thanks and I'll try to get some pictures up.

The first thing to do is check your water parameters. Do you have a water test kit? If not usually a local fish store can test it for you.

Usually I find a good gravel vac/water change will solve a lot of minor issues.
