I was kind off disappointed about the fries. I would said at least 80% of the fries have straight tail. From my observation, the straight tail fries are swimming faster, eating more, and growing faster compared to the tiny fries that have rose tail. As the straight tail got bigger in size...
I have 1 female oranda breeded with 2 males oranda. Some of the babies (about 1 month) have straight tail like comet goldfish tail ? why is that? Can someone explain why. Thanks
