Yes, he is, and like I said, I suspect he has other health issues that are likely due to poor genetics. He has chronic SBD problems, he can't hold himself up normally (his back end is always lower than his head) and sometimes he stands on his tail or floats vertically, which I've been told is not a good sign and usually means their time is near. He also has quite a bit of fin damage, probably from getting it caught in stuff, possible tail biting from boredom, and also the fact that he is a CT and I have more alkaline water.
But I've had him since the middle of November, known he was blind since around the middle of December, and he's had that buoyancy and virtical floating issue for awhile and he's still alive. I can't say he's the happiest fish ever but he's seemed to come more to terms with it. Plus, he has his own 5 gallon heated tank with adequate water changes, VitaChem, and high quality foods.
