Natural way of getting rid of crabs?

[plancton]

Well, I check my tank at night and I see its full of crabs of the undesirable kind. The problem with this is that I see them harrasing my bubble tip anemone and my clowns. My anemone was hidding for a long time and I couldn't find the reason, but maybe this is why.

Are there natural predatord or organisms that might scare the crabs?.

I used to have a banded coral shrimp and when he was alive I used to see less crabs hanging out, although that was on my old tank, and this new tank has new live rock, so I can't tell for sure if the banded coral shrimp was helping.

they sell a comb at the pharmacy...

Is that a joke?, cuz I'm not "getting it".

boil your crotch.

get a trigger?

lol. Minds in the gutter.

Some triggers and wrasses eat crustaceans. Or you could go gangbusters and pick up a Mantis ;)

I got 2 fairy wrasses, they don't seem to do anything about it.

Try something like this:

Put some food in the bottle and the crabs are likely to climb right in to get it....but likely won't be able to get out.

The trap is the best bet, as anything that will eat the crabs could pose a threat to your fish as well.

chef's trap is a great idea. even simpler is to lean a drinking glass against the rock work and bait it. the crabs will drop in for the bait but won't be able to climb the smooth glass to get out

It's not natural per se, but I got two words for you:

I've tried it before, it didn't work! not a single time.

A sixline wrasse?

Shampoo.

Im sorry I had to do it.

The bottle trap has worked nice for me in the past.

Unfortunately I had a few of those hairy crabs with black claws in my rocks. After failing to talk them into climbing out of my tank peacefully, I resorted to semi-violence and tried using tongs to pull them out, chop-stick for impalement and kalkwasser to force them out of the hole. All of those methods failed pretty miserably. It wasn't until I pulled the entire rock out that I could force them out.

They're extremely hardy and resilient. I wish all my corals and livestocks were like that.

If you know which piece of rock he's in, set it out of water and he won't be able to "breathe". This is what I do to get my pistol shrimp out of little holes in the rock.

I've had success with the trap door type fish traps... You might try baiting one of those guys and putting it near where you spot the crab. They aren't too expensive either.

A mantis shrimp will NATURALLY take care of your crab issue in no time. Of course, it'll take care of all of your other invertebrates naturally as well.
