...it was too fast.
His name was Phycondrias...or just Phy...sometimes fishy....he was a beautiful cobalt veil-tail. A moody king of the tank with a habit of biting his own tail...
...he didn't seem sick, only a little lethargic and only for a few moments, then he'd be up and about, patrolling his tank, flaring at me every now and again, but always willing to do his welcoming wiggle like the others...
...I was focussing on the water parameters for the 10g when I looked over and saw him slightly listing to the side, and his head doing some sort of tremor or convulsion...and when he tried to take a breath at the surface he didn't break the surface, he wasn't getting his breath...
...I immediately prepared my shallow qt 'tank' for him, warm water, 1 tsp epsom per gallon thinking it was some sort of SBD or inflamed gills...when I put him in the qt he swam just a little then stopped, started listing and I saw his gills weren't closing all the way...then he convulsed again, his whole body doing this scary tremor and then it stopped...and he stopped. Everything stopped...
...I don't know what I did wrong...I was too late to save him...
I'm sorry Phy, I failed you, and I don't even know how...I didn't mean it when I called you a brat for always tearing your fin...I love you, and I'm so sorry I couldn't save you...
Rest in peace, my lovely little blue guy...Phycondrias.
