well i bought a male mandarin goby about 3 months ago, i have bought several pod cultures from inland aquatics to try to keep it happy. but the good news is that its startin to eat live bryme shrimp. the mandarin and my green banded goby are startin to hang out together too. its kinda neat the way the mandarin will be sitting almost on top of the green one. it looks kinda like a big dog protecting its puppy.
