SRC Member Vincenttan Posted February 27, 2004 SRC Member Share Posted February 27, 2004 Hi Bro, I discovered a big hairy crab inside one of the hole in my LR. I try to put bait in bottle and trap it but unsuccessful. One of my crown fish is dead due to this crab. Can someone help? Quote Link to comment Share on other sites More sharing options...
SRC Member aStRoBo| Posted February 27, 2004 SRC Member Share Posted February 27, 2004 take out the LR, soak into higher salinity, for eg. 1.030. they will climb out. worse come to worse, soak into fresh water, not recommanded though as good bacteria will die off.

SRC Member Acanthurus pyroferus Posted February 27, 2004 SRC Member Share Posted February 27, 2004 usually with high nitrate in the tank from feeding and dosing additives the crab will be poisoned to death. Found many of my crabs dead on the sandbed.... Easiest way to get rid of them but still a few more tough ones around which can overturn some of my corals....

SRC Member Siput Posted February 28, 2004 SRC Member Share Posted February 28, 2004 Does the higher salinity thing work well? How about on other creatures such as mantis shrimp, etc? Quote Link to comment Share on other sites More sharing options...
SRC Member rockfish Posted February 29, 2004 SRC Member Share Posted February 29, 2004 i try curing some untreated LR with super concentrated salt water. it worked .. all the piston shrimps and crabs all crawled out of their holes .. i soaked the rocks in the conc salt water for 30 mins. when i take out the rocks, all the crab and shrimps and bristle worms alll out at the bottom of my plastic ontainer.

SRC Member arcanehacker Posted March 6, 2004 SRC Member Share Posted March 6, 2004 :? you got shrimps? Or any slow swimming fishes? .. the octopus will also eat them..
