Moonshoes was battling with a bit of sbd from the new water and acclimating to slightly colder temperature while we set up the heaters.
Unfortunately his sbd issues lasted for 2 weeks, but were on and off.
I was treating with epsom salt as per usual, but it seems like the new conditions and his age were just too much for him. He was older, I know, when I bought him, and I had him for a few months shy of a year.
Farewell Moonshoes Potter.
