Hey
Sorry I wrote a long message saying how wonderful I think your tank(s) look, and how much of an inspiration these journal threads have always been to me, esp when still a novice at the hobby.
The bulk of my original message was talking about your C.strigosus but I thought the last page in the thread was 4, and it was only after that I realized on page 5 you gave the grim news of his death
I have kept four pacific Koles over the past X years, and one of mine also died from the same reason - a series of unfortunate events lead to a dramatic drop in temperature in, ironically, his QT. My other three are a live and vibrant; one enjoying his new home with a close friend of mine. They are really wonderful fish, and I hope you decide to get another one day.
Keep up the good work and I wish you years of success with your upgraded system! I'll be checking back often no doubt.
-Alex
PS - was also fun to watch your photography skills improve
