Melev's Mandarin Diner
For a long time my blue mandarin was a very happy fish in my 29g, and would eat prepared foods much to my delight. Since that was the case, I never worried about it. However, in the 280g reef, it was actually being starved to death due to stress by the other mandarins harassing it as well as the voracious Tangs that would circle around it and get every morsel of food off the sand.
