Well the tank temperature is kind of the problem, as every day my temperature fluctuates from 78ish to 80ish, and that is the glory of Texas. I have been able to cool down the tank whenever it overheats with a fan. I did have the tang running a full copper but then I was able to catch another fish that had been surviving in the main tank and added it into there, and forgot to increase the copper again. The only thing that I can remember that was ever shared was a net.
Can you clarify the part where you “caught another fish surviving in main tank”? When you caught this fish, both clocks need to reset, the copper treatment period and the fallow period. Did you go fallow another 45 days+ after you caught the last fish?
BTW, I see nothing in the video of concern, but if you can see them the concern is still there.
