mandarins are probably oneof the hardest fish to keep. I recently added one a few weeks ago, an ORA tank raisedone that was supposed to eat pellets. paid alot for it too but all she will eat right now are pods
and cyclops and some plankton. Their diet in nature is 100% pods
. if you have a refugium or a fuge you can add pods
into there and hope they multiply. I have a fuge and I don't have that many pods
in my biocube and I even seeded it with a bag of pods
A mandarin can go through a couple bags of pods
a week, when i say all they do is hunt for food I'm not exagerating. Mine is literally on the hunt 24/7.
An established tank with ALOT of rock and a refugium is the way to go in my opinion.
How big is your tank btw?
