Dead Bloodfin ?

[depthC]

I just recently had a bloodfin die for no real reason. Ive had all my bloodfins for almost 3 years and this death made me not so happy and on top of that i couldnt figure out what it was. So im here for some help.

The water conditions are fine and all the other fish are active and healthy so i dont see were the problem came from.

My bloodfin was floating head up and tail down, he couldnt position himself like normal because his head wanted to point upwards i guess. I couldnt figure out what this was. He couldnt eat, he couldnt stay still, all he could do was sit on the bottom. It also didnt help that i found my CAE sucking on him while he was still alive. So i just let the fish suffer. I knew if i quarantined him it wouldnt do any good, prolly just stress him out and lead him to death faster. So he suffered for a day and finally passed away. What the hell was this? A disease or what. Thanks
