I did a ton of research before purchasing my regal angel and I took the route of eliminating any possible stresses during the first 3 weeks of acclimation. I did this by acclimating him solo so he didn't compete with any other fish, no lights for the first 2 weeks, and keeping water quality pristine and as close to natural sea levels. It took several days for him to start eating but now he eats everything I throw in the tank. I initially enticed him with raw oysters and clams. Kept feeding fresh raw and then moved to frozen food after a couple weeks.
If he has a parasite this is just another added stresser but if he has started to eat then I'd wait and see if you can get a good meal in before treating. I suggest conducting a FWD first off to identify if you're dealing with flukes. As mentioned there is the TTM or if go the route of medications, the copper treatment will suppress flukes buying you time to eradicate ich first and circle back around to treat the flukes.
Scenario 1 (with only 1 QT tank in rotation)
-Copper at therapeutic levels 35 days
-Add carbon and conduct large water change at least 50% water volume
-Make sure fish is eating
- 2 rounds of Prazipro as directed on the bottle
- Observe for 2 weeks
Scenario 2 (with 2 QT in tanks in rotation)
-Copper at therapeutic levels 14 days then transfer to sterile tank
-Make sure fish is eating well and then administer 2 rounds of prazipro as directed on the bottle
- Observe for 2 weeks
Scenario 3 (with only 1 QT tank in rotation)
-Copper at therapeutic levels 35 days
-Make sure fish is eating
-After two weeks in copper, dose 1st round of API general cure wait 5-7 days, conduct 25% water change and conduct second round wait 5-7 days (Must make sure to hold therapeutic copper levels, its not advised to mix medications but GC and copper can be combined. Have done it on many occasions without ill effects)
- Run carbon and conduct 50% water change and observe for 2 weeks
The challenge is to make sure you keep copper at therapeutic levels which means you need to pre dose medication in your fresh saltwater batches prior to adding it to the QT tank.
