Well, I've only tried this on the one rescue fish, with poor results. That particular mandarin was really too far gone to respond to anything.
BUT, the theory is sound, and there was a big spread in the December issue of CORAL that details this procedure as well. If you're serious about weaning a Mandarin onto frozen or pellet, you start with a healthy specimen. Look for one who is exhibiting the hunting reflex in the store. If he's eyeing live brine already, so much the better.
Take the mandarin and house him in a net breeder, thereby seperating him from the rest of the tank for a while, and allowing him to feed unhindered by the other fish. Put it in an area of moderate flow, so (a) wastes can be flushed, and (b) food will be trapped against a side. More on this later.
When the fish is in the breeder, start tempting him with live brine shrimp. The wriggling motion of the brine will act as an attractant. The FLOW we just mentioned will push the live brine against the side of the net breeder, which helps stimulate the mandarin further -- their natural inclination is to pick their food off a substrate - in this case the net wall. Now you have a wiggly food in a position to be picked off in a manner that's most natural to the fishes instinctual way of hunting.
Be patient. Again, I HAVE NO DIRECT EXPERIENCE WITH THIS, but I can imagine this is going to take some time before the fish decides to try a brine shrimp. Eventually, though the fish should start taking live brine in this manner.
Once your fish is used to taking the live brine, start switching him over to frozen. Some people in the seahorse world recommend you start slow by chilling live brine down to where they're almost non-moving, but still alive, and using these near-death shrimp as an interim between live and frozen. Regardless, the dead frozen shrimp will ALSO be forced up against the side of the net breeder -- just like the live ones -- which is partly why the recommendation to keep the net breeder in some flow makes so much sense. To the mandarin, the food is in the same place it always is, so the desire to eat should overcome the possible aversion to dead food.
As a final move, AS SOON as your mandarin is eating frozen brine, switch him over to frozen mysis. I would probably use the mini-mysis frozen variety first, since the size is comparable to brine shrimp.
As a final note, many mandarin keepers have mentioned that live tubifex worms or live black worms are also a great mandarin appetite stimulator. You may be able to use this procedure with those foods (live, then frozen, etc) in place of the brine shrimp...depending on what you can most easily get your hands on.
Awesome info!!!
