Ok so I am totally new to this site and to being a fish owner. But since I am new here I have no idea where this post should go so I thought I dhould put it here since it has to deal with goldfish. But I need help. This last weekend I got 2 goldfish and a tank(small right now but am getting a 40 gallon on thursday from friend after learning about minimun size for tank and goldfish. So thats being taken care of.) I have a smaller black moor was nipping at my calici ryukin goldfishs back tails but did stop and there is absolutely no damage. My problem is that calicos front fin on the right side is like gone. he pretty much looks like nemo sorta. Now im not sure if it was lije that when I bought him or after I hoylused him. Im,almost positive it was not the black moor but ya. Should I be worried? Can anyone shed some light on this? I kniw its not fin tot cuz I usedto has guppies and one got it so I know what it looks like. Any ideas ad to what ot is or ehst caused it? Should I be worried?
