I just got a grey-belly IO Regal Friday. I have been prepping and planning for a few months, including reading <most of> this thread. I got him from my LFS who ordered him, and I got him fresh off the plane in the bag. Unfortunately he is a bit bigger than I had hoped at 4.5", but I am cautiously optimistic:
He came in with flukes--treating with Prazi in a 20 gal QT with a few chunks of LR and some clay pots. I started treatment Saturday am and he has seemed to liven up since then.
Eating wise, he has been timid (big shock, no?). I tried a clam--littlenecks, I think--first. He came to it and tore a bit once, swam around for ten minutes or so, and then came back and tore another tiny bit. I left it in there for two hours, and it certainly wasn't gone or mangled, but it did have a few nips out of it. I took this as a good sign. I also tried PE mysis soaked in garlic (probably won't do this any more for I think it is rather mythical) and some Vita-chem. He noses everything like he is interested, but seems non-commital. I have also tried NLS pellets. Again, seems interested but not wolfing anything. Most times he nidges things once they have sunk to the QT bottom. HOWEVER, I have seen him eat a few mysis, including once from the water column, and he has eaten a few pellets and continues to dabble in clam. Nothing voracious, but is consuming some things. He tore a tiny bit at some nori and seemed a bit more interested when I banded some feather caulerpa to a rock today. I'll see tomorrow if he took to it more (oh yeah, he is in QT waiting for the DT in the library at Columbine High School--not ideal to not have 24/7 access, but the tank is eleven years established).
MY QUESTION:
Many people in the thread suggest that regals do well when introduced into the display because other fish "teach" them or "model" for them how to eat from the water column. I do not think mine is ready for the DT yet, seeing as there is a small yellow tang and a small kole tang--both smaller than the regal (in a 225). They both are generally peaceful, but they are excitable at feeding time.
Should I purchase/borrow/rent a small fish to add to the QT to help teach the regal to eat? Something peaceful and not an aggressive eater, but one that will readily eat--a blue/green chromis or something? My LFS would certainly allow me to do this, keep him in QT, then return him when I am finished, as long as it is not some $50+ fish.
Is this even feasible or worth a shot? Or would it cause more stress for the regal? Someone back in the 200-300's seemed to suggest including "dither" fish like this as a training tool. Is a 20 gal too small already?
