When i lived outside of California, my old female marbled motoro. Friendliest, most active ray I had ever had the pleasure of owning.
Red oscar. Recognized me and learned how to do tricks. I cried when i had to put her down. My knowledge in fish meds was limited at the time.... still feel sad when i think about that oscar.
Currently, a one eyed 12"+ TATF. It was born with one eye....it looks like a skull on one side. Lets me pet it. Raised it from 2.5"s. At 5"s it developed an eye infection on the other side.... it stopped eating for 2 months... almost put her down when my wife called me and said it started eating. Just by instinct it began eating daily.... with it's "good" eye covered in a white fuzzy patch. Miraculously a month later, it's eye began to heal. It is without a doubt my favorite fish atm.
my own was a black convict I had for a couple of years, tough little guy that would always inspect everything; and bite test it lol. Lost him mysteriously when he stopped eating, I suspected parasites; was gutted when he popped it.
