So - 30 days copper power >1.75 confirmed daily (Hanna), Immediately followed with 14 days in Hypo 1.009 confirmed daily w/ MKE meter and hand held to deal with prazi resistant flukes. Moved gem tang to New (fishless run in) DT along with another damsel that has been through same cycle- 1 day later Gem has a “twitch” only on top fin (not head twitch like flukes) and a white spot appeared on his right side fin. Incredible. Parameters all good on new tank. Stress spot? Damsel is fine right now.
What does the spot look like? Could it be lympho?(fingers crossed)
