Walter, I was thinking about a few things when I decided to cut the QT time short
I've lost fish in QT before and wanted to avoid it for their benefits
Why risk healthy fish due to paranoia ?
Top of my list was a bunch of wrasses that may not do well in a small tank with no LR etc. I use a tray of sand, but only 2 of the 7 fish were using it, so the rest were 'hiding' behind stuff at night. I felt they could be happier
Next thought was they look good, are eating very well and if they had MI, now it's in the QT so I'll get them out before it hatches and jumps back on them. And if they had MI at the time, they would have shown signs, which they weren't. No flashing, rapid breathing etc. And by 2 weeks, if there were any other nasty diseases it (hopefully) would have shown by then. As I stated, they were all perfectly healthy with no marks, worms etc
Third thought was I couldn't feed them as much as I wanted to without doing more than one WC per week as the AC50 couldn't keep up and I wasn't about to lose another wrasse due to high NO3. I wanted to ensure they stayed fat without risking their health
And as I also stated, they were eating everything I threw at them, so they had to be in good shape
There was no point in hypo, and waiting 6 weeks was going to be a risk of their lives
That's about it
