I would watch it VERY carefully. Just because it eats prepared once or twice, doesn't mean that it WILL eat it long-term. You need to remember to rinse the frozen food in RO
before it gets put in the tank. The food will also need to be vitamin fortified as they don't get all the nutrients they need from non-fortified. I would find a way to feed it instead of just tossing the food in. Mine has adapted to the "Mandarin Diner". If you just toss in the food, make sure you put it in ONE spot every time so the mandarin knows where the food is. I would have a bottle of pods
on hand just in case something goes wrong. HTH
My personal experience is that they are very entertaining fish and have a great personality with lots of color, it's just they need the extra care to make sure they get fed properly. Watch the belly, if it caves in, you WILL need to add pods
to the tank which will get expensive. The best option would be to find someone with a stable tank of 100+ gallons that can mantain the mandarins diet. Once again I hope this helped.
Just letting you know what you are in for.
