Animals are already in copper tank getting treatment. I just want to confirm my suspicion that this is velvet. Thank you ahead of time.
Some additional info - super quick onset after lights were increased in power. lost 4 fish within 48 hours, 2 24 hours later and 2 48, they showed no sign unfortunately so I couldn't catch it earlier. Caught everyone else and moved to a QT tank with copper. Only the tang is showing signs and is fully covered now, but everyone is getting treated.
Another question I have, how long would it take for the tang to get some relief in Copper.
