Achilles Tang Posted September 17, 2003 Share Posted September 17, 2003 I was wondering why a few of my acro colonies didn't have polyps extended and then I saw it... hairy acro crabs... known to eat acropora polyps and doing just that!!! AARRGGH!!! Out came the pincers and gotcha... the big ones got the sharp point into their mouths and instant death... the smaller ones got yanked out. Danano was at my place a couple of weeks back and his sharp eyes spotted one on my blue tort that has a receding patch... and yes, you guessed it... a tiny hairy acro crab! I seemed to be hunting crabs with a vengeance now... just took out 3 crabs... biggest one had a carapace the size of a 1 cent coin. They are easily IDed by hairs on their legs and they seem to have whitish/blue eyes. Their claws also have black-tips. These are definitely not filter-feeders like the smooth and white Porcelain Crabs that inhabit acropora corals. Quote Link to comment Share on other sites More sharing options...

SRC Member nleong Posted September 18, 2003 SRC Member Share Posted September 18, 2003 While I was moving some LR last week, I saw one as big as 1" climbing around the stack of LR which have been left dry for weeks. Imagine their survivability. I know I still have one in my tank, just cannot find it. Btw, what about those commensual crab that comes with acro, those should be alright right ?

SRC Member pospeh Posted September 18, 2003 SRC Member Share Posted September 18, 2003 Hey it's Hairy Crab season now. Love those roe. Maybe you can find a big 5 inch specimen and sell them to the restaurants. Quote Link to comment Share on other sites More sharing options...

Actually, yours may be a different species... no way these crabs can survive even 24 hours without water. They dehydrate and die. The ones I caught last night at 12 midnight are already dried and dead this morning! Commensual crabs are different from these crabs.

SRC Member nleong Posted September 18, 2003 SRC Member Share Posted September 18, 2003 Well, I don't even bother to go look at it. after finishing removing the rocks, i just wrapped up the plastic bag and throw into the chute. Not sure if its still alive somewhere in tampines. Quote Link to comment Share on other sites More sharing options...
SRC Member Dazza Posted September 18, 2003 SRC Member Share Posted September 18, 2003 These hairy crabs are very common in rocks of local waters. Almost every piece of rock collected locally has one ot two in them. best to get rid of tem as they attack fishes when the fishes are asleep.zzz zzz zzz, Ouch!!!

SRC Member Cookiemunster Posted September 18, 2003 SRC Member Share Posted September 18, 2003 Sigh no wonder my poor firefish and purple fish have all disappeared. I had 6 of them and now left with two. Quote My Humble 4ft tank Link to comment Share on other sites More sharing options...
SRC Member Tanzy Posted September 18, 2003 SRC Member Share Posted September 18, 2003 I've never seen the rock hairy crabs attack acros before. It's always the type of hairy crab that's already on the wild colony that eats the polyps. I'll always pull them out before I epoxy the colony down and feed those furry guys to my hungry hermits.

SRC Member Chris Posted September 18, 2003 SRC Member Share Posted September 18, 2003 My acro is too dense and my pincers cannot reach in to pull out the crabs. How? Any other ways to get the crabs out. My acro doesn't seem to be suffering from the crabs? Quote I think (marine) therefore I am Link to comment Share on other sites More sharing options...

Achilles Tang Posted September 19, 2003 Author Share Posted September 19, 2003 I use the business end of my pincers to give it a death blow. The corpse will release its grip in the acro branches and fall out/be pulled out easily. Quote Link to comment Share on other sites More sharing options...
