Bubba died a couple of days ago. I don't know if it was ich. (The only decent pic of him is included, and it shows the dorsal area to his peduncle.) There are no white spots on my two remaining goldfish. So, for now, that is not an issue. I did get my Freshwater Master Test Kit yesterday. My results were/are:

             yesterday today
PH              8.4        8.2
Am               0          0
nitrite           0          0
nitrate         20         0

It was a 50% water change, and I boiled my driftwood to extract some tannin. I also added Seachem's Prime water conditioner.

My two remaining buddies, Spenser and Hawk look all right, but I think a 50% water change is potentially tough on goldfish in my situation. For me, too many ways to screw up. But I think I've done good, and I am content at this point.

He seems stressed.

OMG  it does pay to read the first entry sometimes...sorry for your loss trft R.I.P. Bubba

I know but before he died he was stressed!
