Nah, not overweight, just a normal healthy mandarin. If you see them smaller than that, they're suffering from malnutrition. An interesting note... this guy now eats from the water column. When I drop in frozen, he comes up and snatches it with the rest. Started with mysis and now he even eats prime reef. Loves his baby brines when I make them, but my airpump went belly up so I haven't hatched any in ages. My pod pop is still booming too. I add about two lbs of red gracilaria every few weeks, that helps.
Only thing more dangerous than a 2nd lieutenant saying "In my experience" is a warrant officer saying "Hey guys, check this out!"
