I haven't seen mine picking at anything. He's usually eating algae off the rocks. The only thing i don't like about them is thay are bigger than most crabs i have. I would recommand the Pom Pom crab. They are my favorite crabs.
I have 3 of them in my 125 reef and they do not harm anything. They like to hide most of the day but come out in the evening and walk around. I love mine!
K, it's settled, I'm gonna buy one. Thanks all.
I was in houston about 4 times back in December. I was very lost. My town only has 250,000 people, so it was like the beverly hillbillys trying to find their way around Southern California.
