All is not well; the importance of quarantine
I haven’t been able to set up the old 10 as qt yet as I still need a few things and just haven’t gotten around to it.
But the tank was doing extremely well. All 7 fish happy, active, and spending in the open at the front.
Since the water parameter were good we decided to get a few more. Risking it just one more time.
Grabbed 5 from the LFS they looked pretty small, pretty pale, but they had just been received earlier that day so it was to be expected.
Only two made it home, one didn’t last to the night. The final was picked from the filter two days later. Long story short, of the seven happy healthy fishes, two remain. I don’t know what’s causing it. The water is still testing fine. Nothing else has changed since the happy healthy fish 6 days ago.
