So I have noticed that the fins of five of my silver dollars are getting nipped up pretty bad in my 225. No matter how much the wife I try to watch them we can not find what fish could be the culprit. These five silver dollars stay in a school all of the time, the sixth one is a loner and his fins look like normal. So does anyone think that I could have a school of silver dollars that bet themselves up as a group. The rest of the fish in the tank have no signs of any nipped fins either. Will there fins grow back with time and is there something that I have over looked to prevent this? I am just getting irritated with this, but thanks for your input.
