hairy crab

[absolut_vodka]

I just found a small tiny hairy crab in my tank (about 1cm big). It lives in the little holes in the rocks. Is it harmful to my fishes and corals? Should I remove it? I believe it came together with the live rocks.

Enough has been said about crabs - remove it immediately.

There's a very successful trap proposed by one of the reefer here using brands essence bottle...

I managed to caught 3 with this trap

Usable only if you don't have any ornamental shrimps such as Cleaners, Blood etc ... otherwise, it'll easily pick at the food.

Small fishes or those with slimmer profile such as Dottybacks may also get to the bait.

Try using baitmeat in a mesh bag or stocking, last I heard, crabs get trapped in them easily, but that may also be the case for shrimps.

My hermit went into the brands bottle the first time i use it...

So i blocked the entrance using a branched LR and leave a small opening for the prey to go in

It works alrite...

hmmm bros, i've been searching for that thread by a reefer who discussed that brands essense of chicken bottle trap. duno if i just blur but my search keeps landing in a thread where a bro will suggest to find the said thread.

i guess i just blur, but could somebody post that thread link here

is there any fish that is a natural predator of crabs?

[terryansimon]

it just is a brands essence of chicken bottle, wash clean with fish bait inside. you may want to wrap the bait up with a bit of netting to prevent fishes from prying the thing away.

angle the bottle in such a way that it has an opening. angle it against the rock, and wait till the next morning to fish the crabs out.
