I meant to write sooner, but December was a crazy month for me. Great White Shark died in early December. Her last days/week were not good at all, and I thought often about ending her life myself. She wasn't able to swim at all in the end and would stay put in whatever position she was (on her back, nose down or similar). Once in a while she would use her fins rapidly and move a bit only to end up in another hopeless position.

Anyway, I never found out what she had. Someone said that swim bladder issues are common in feeder goldfish and they sometimes swell up as well.

We now have a new beautiful male (gorgeous pinks and reds) named Jupiter. I really hope we will have him a long time.

Thanks again so much for your help!
