Help! I just did a water change in my community tank--all kinds of tetras, algae eaters, and silver dollars--and I tried this new stuff that was recommended to me called Fresh Trace, to put some minerals and vitamins back in the water. Well I literally just tried it and now my silver dollars are turning orange and I have never seen it before. Their fins are turning orange, around their gills, and above the darkish horizontal line down their bodies. I have rummynose tetras and their faces are still red, so I can't figure out if something is wrong. Help, I'm worried they are dying!
