I've had this weird Emerald Crab for the longest time and he's not acting like an Emerald Crab he's acting like a Coral Crab! I moved him from his Coral on some Bubble Algae I want him to eat but instead of eating the Bubble Algae he walked right back to his Birdsnest?! When I try to frag my Birdsnest he'll even try his hardest to pinch me I'm thinking either I have a defective Emerald Crab or it's a Mimic Coral Crab
