I have a large Regal just arrived yesterday from Live Aquaria, I'm quarantining with one of the XL flame angels Divers Den has had recently. I had a plan of slowly adding cupramine at roughly half the recommended speed, and then holding the dose for about 3 weeks before moving them into the display, fully expecting the regal to take roughly that long to begin eating anyway. I've had success with 2 regals in the past, but had to trade them in after two years. One took two weeks to eat, one nearly a month.
This one was picking leftover mysis off the bottom of the tank minutes after acclimation. After I got home from work it ate everything I threw at it, even some flake and NLS pellets. Devoured a clam. No one more surprised than me.
Should I still treat with cupramine as I normally would, or should I not mess with a good thing and just keep an eye out for problems? I don't want the feeding response to change.
I should add, I did see a little bit of glancing from the Regal and the tail fin appears to have a cloudy spot. Not sure if it's anything or not, and let's just say it wasn't the smoothest acclimation so it might be a little injury from that.
