Their temperature requirements are between 65 and 75 degrees Fahrenheit. My "cold water tank" is about 70. It's cooler than a typical community tank, which is why I described it as cold water. Though 70-75 is typically suggested, I've had more luck with slightly lower temperatures with all of my platys in the past. I'm not worried about water parameters or temperature for this tank. I did increase the temperature of his hospital tank by a tiny bit. It's smaller, so it's a bit warmer.
But my other platys have thrived under nearly identical conditions.
I'm fairly certain that it's an intestinal blockage but I've never encountered swim bladder issues in my community tanks in the past so I can't be sure.
