NO!!!!!!!!!!!!! What people fail to understand is that dragonets require massive amounts of established rockwork (ie 75lbs or more and have been stocking with copepods for over a year) in order to support a very large and self sustaining copepod population (it's natural food source). You can't fit 75lbs or more of rockwork in that config and that is what you are going to need to establish it's food source. The only way I could see it working in the config you mentioned is if you had a fat mandy that readily accepted frozen food from the fish store before you bought it and even then you would need to turn off the powerhead and target feed with something like a turkey baster since they are very slow and methodical eaters. The Mandarin actually shares a number of similarities with a hummingbird in slow motion. It cocks it's head to the size and flutters it's fins like a hummingbird flaps it's wings. It also takes about 3-4 steps to eat food that is right in front of it's face. I had a Green Mandarin that lived about 3 months in my 36 gallon and I spent nearly $300 in copepods in that time trying to keep it fed. It learned to eat Frozen Mysis and Reef Frenzy but was too slow to get to the food compared to the other fish. It actually had to fight my cleaner shrimp for food. Cool looking fish with interesting characteristics but any love I had for the fish died with it. Way too much hassle for my tastes.
