All my goldfish are commons and comets, except one looks nothing like the others. It's a single tail, roundish, and slender. Its shaped the way fancies are but it has a single tail and isn't fat like a fancy. as far as I know, only commons, comets, and shubunkins have a single tail and this fish looks nothing like any of them. This guy actually kind of looks like a orange and white angelfish but without those long things hanging off its stomach area like an angelfish has and it's top fin isn't as tall as a angelfish's. Any idea what this guy could be? I can get a pic tomorrow if you need one.
