It's a lyretail sailfin. She is HUGE, but not balloon. I bred this fish, I have 3 generations of her parents lol.
I did shoot a little video on my phone and upload it. I've set her up in a 10G with salt and high heat hoping maybe that will trigger SOMETHING. I do fear everything inside of her is dead and just blocked up, but this is my last resort.
