So I was wondering if anyone has ever heard of anyone using goldfish as tankmates for jags or jacks? My girlfriend has a couple big goldfish that are around 5"-6" and I was thinking about maybe trying to put them in my tank that contains a 3" jag and a 3" jack to liven the tank up a little. I don't know if this is even possible but I wanted to see if anyone has heard of this or maybe experinced it theirselves. Thanks
