eletrocute a tank to kill a crab?

[saf1]

Electricity seems a bit overkill. I would continue to try the traps and use a piece of shrimp or prawn. Also mash up a bit of the food to get the smell going.

Honestly, and not to make light of it, just make a game out of it. Use a Tupperware container, slot the top, toss in the shrimp and mush, put some sand / substrate over the top, see what happens. I had to catch a Gorilla crab once and this is what I ended up doing although I actually put a fishing swivel through the lid and base, some line, and added a rock inside to weigh it down. Then I picked a weekend, loaded it up, and waited for it to get there and snack. Then pulled it. It couldn't get out

Anyway - bummer for you and sorry to hear about the frustration. Hang in there. You will win in the end.

Hiya stranger!
:wavehand:

Hey John how are you ?

If you do go the electric chair method please video it... I want to see how it goes

 

[ReefCowboy]

This is funny...made me laugh when i read it

 

[Darryl Hey]

I could use a good laugh

Aside from leaving scorch marks on the glass of your aquarium (assuming the glass doesn't blow out) you'll be creating a dead short.

I'd recommend wearing sunglasses.

If he only puts the hot wire in it won't blow up since water is conductive. Just don't put the neutral in other you will bow up pretty good

Only put black wire in water put don't ground or neutral in. Or you'll blow up pretty good

No better way to start the day than a little head banging!

As far as blowing things up, if there was too little resistance, the 15A breaker would go. Years and years ago, I put the hot and neutral 110V wire into freshwater and it didn't throw the breaker or cause the water to explode or anything like that. I think salt water would throw the breaker, IDK, but I've backed off electrocuting the tank.

I used a 1 liter wide mouth water bottle, cut the top off and inverted it, taped it together and added fish food and a mantis crawled right in. I would think it would work for crabs also? Glad you gave up on the shocking idea.

reef theif you kill me!

Reef Theif you kill me with "Smoke It!" hahaohoahoahoah

I think electricity is wrong way to go...just nottttt a good idea...

Keep trying to catch it...you'll catch it and then trade it in at LFS....easy

and humane..>I know its just a crab but.... trade it in! Someone will have

a preditor tank for it....it might be lunch for a moray...you going to deprive

the moray? lolol

Put 2 110W lightbulbs wired in parelle in series to limit the current.

Black wire ---------[bulb]--------- probe
White wire -------------------------- probe

Taser? Cattle prod? Scuffle around on the carpet for a few hours and then touch the rock?

I had a Xanthid crab which caused some collateral. I tried the bait method using prawn etc. in a glass tumbler. All I got was everything but the crab.

He lived at the base of a small rock island which would have been a pain to get out as it is zip tied and cemented with all sorts of things in it.

I decided to purchase a powerful air pump and attached both outputs to a single air line.

The end of the airline was placed inside the foot of the island, turned on the pump to low. It gave a rather nice effect!

Within a few minutes the crab came out and was dealt with.

Get a trigger or puffer, it will make short work of your little crab. Return the said fish to fish store when it's done with its snack

 

[Digitalelectric]

That's a porcelain crab that's very common in the waters here in Florida. Where did your rock come from? Those are completely harmless.

 

[Reefkeepa1]

Even if you did "electrify the tank ", that crab would never know. It wouldnt accomplish anything but you needing to replace the breaker you blow up.

 

[salty joe]

The rock came from Jakarta, Indonesia and was very fresh.

I thought about adding a trigger, but there are so many hiding spots a fish could never get to.

You can touch the hot and neutral wires and the breaker just trips. So the breaker wouldn't need replaced. I'm not going to try electrocution though.

I've only seen the crab twice and one of the times he was working on a snail, so I'm pretty sure it's not a porcelain like the one I pictured. I've gone months without feeding trying to starve it, I wish there was a way to know if it were dead.

Yea please do a video.

Electrocute a tank to kill a crab is like nuke a city to get rid of a small time criminal. Think of something else, especially for what seem to be a harmless, and nice porcelain crab. If you get good rock, there will be plenty of hitch hiker. Don't assume that they are guilty unless you have evidence of it, or at least accurately ID it.
