Mandarin are one of the most beautiful fish in the trade, they are also one of the hardest to keep. If it was possible to keep one in an aquarium as small as a 10 gallon, would you? The fish would be well fed, comfortable, and happy. You also wouldn’t have to worry about the normally expensive cost of feeding it live pods every day. If yes, why? If no, why? Thanks for the info, this is important data. I love reef2reef for this stuff.
