Hey, Art, I'm really sorry to hear of Phred's demise. It's hard to lose one of the "kids," I remember when my betta died after 3 years.
I remember your postings about him; the ailment was so similar to my dwarf gourami, who swelled enormously with no other indications. Nothing helped, and when he stopped swimming/eating I euthanized him. It was so hard, but for me it becomes a quality of life issue. He was staying on the tank floor, fins clamped, looking miserable.
We have memories, we move on, and they always stay in our hearts!! Take care.
