OrangetheClownfish Posted January 11, 2016 Share Posted January 11, 2016 Hello guys I was taking a look at my small piece of live rock and i found out htere was a crab living in it. I got that rock when I bought a cluster of yellow polyps from Fresh n Marine shop @ macpherson. About a few weeks later the polyps died, and so i just left the rock there. Only about close to 1 WHOle yeaer later, I took a close look at that rock by picking it up and out of the water, and saw dat crab. More bout da crab: about 1 cm or smaller in length, saw it only for a few seconds and told my mum and then it hid back into the rock. ANy idea what species it is? I mean, possible species? It's grey brown with some stripes, that's all i saw. Quote Link to comment Share on other sites More sharing options...

volkim Posted January 12, 2016 Share Posted January 12, 2016 I'd aim to remove it, I had 3 crabs in mine, and it took me 2 months to finally get rid of them. Quote Link to comment Share on other sites More sharing options...
OrangetheClownfish Posted January 12, 2016 Author Share Posted January 12, 2016 This morning I got a closer look and its claws had black tips. And so i assume it was nocturnal because in Singapore 6 am is still dark and we are all in sg, i think. Quote Link to comment Share on other sites More sharing options...
SRC Member JMW Posted January 12, 2016 SRC Member Share Posted January 12, 2016 Most hitch hiking crabs are nocturnal. To see them in action, have all lights at night, then with a flashlight you can see them venturing out of their hiding place Quote Link to comment Share on other sites More sharing options...

Tian85 Posted March 17, 2016 Share Posted March 17, 2016 the crab will eat your corals or your livestock. If you have a sump, u can put the crab there Quote Link to comment Share on other sites More sharing options...
