Hi, just got a gorgeous gem tang 9 days ago. Almost 5 inches, fat and looks great. I quarantine everything wet before they go into display system so he goes into my quarantine tank that I usually have set up.
My process is as follows:
- all new fish go through a 60 min formalin and acriflavine bath, heavily aerated water
- in that time I change 65-70% of my quarantine tank water so the copper level (copper power measured with Hanna) comes down to around 1.0 as I usually go to 2.3 when quarantining fish. I leave the water and sponge filter in there from the last set of fish if no signs of disease.
- fish go in QT and copper ramped up to 2.3 over 3-5 days depending on fish.
- fish kept in quarantine for 14-21 days and go to display
Now the gem tang is eating great, but when I ramp up the copper to above 1.75 he starts hiding and is lethargic... I then do massive water change back down to 1 and he’s ok. Twice this has happened which likely means this one is copper sensitive. Have done more than a dozen different tangs and they usually behave as if the copper is not there.
Going to go with tank transfer in 5 gallon buckets but changing water every 48 hours with 5 day acriflavine treatment in water and formalin dip in middle and end of treatment.
Any further suggestions etc? @Jay Hemdal would appreciated your input
