Hi Hennie

I am still a beginner, in week 4 of cycling my tank so still have a way to go yet.

I have found 2 mantis shrimps in my tank and have no idea of how to get them out without damaging them (I didn't want to just kill them).

I can't place them in my sump as there is no room and they are buried in 2 of my largest pieces of rock.
I tried luring them out with pieces of fish but they are incredibly shy and won't come out.

I took the pieces of rock out of the tank last week and put them into buckets but I was going away and thought it cruel to leave them to freeze to death so I put them in the tank again.

They are still in their original holes.

Do you have any suggestions of how to get them out of their holes if I take the rocks out of the tank again?

Hi Mouse,

I've moved your post into a new thread - hope you don't mind...

The easyest way to get the unwanted mantis shrimps, and many other pests, to vacate their premises is to add some carbonated water to a container holding the "infected" rocks. I have found that it works best to take some tank water and treat it in a Soda Stream, just as you would making soda water. Pour this salt soda water onto the rocks in a bucket, etc. and cover the rock with the soda water - the shrimps should come out of their holes within a few minutes, as they will start to suffocate due to the high CO2 content of the soda water. If you want to keep them alive you can just catch them with a small container (drinking glass...) and then place them into a larger container with fresh (untreated) tank water - they should recover quite rapidly.

If this method does not work then the only other method I can suggest is to leave the rocks out of water for an hour or two, but this does not have a high rate of success.

A Beautiful place!
Thank you Hennie, much appreciated! I'm off to go get a few gallons of soda water.
Don't buy soda water, you need to take your current tank water and put it in a soda stream machine to make it bubbly ;)

something that aslo works,
1) get a clear container and place a little abit of sand in it to stop from floating away.
2) cover the top with cling wrap and cut a tiny slit in the top. use an elastic band to hold tight
3) fill with water and place a piece of hack or fish in the container
4) place in the sand as deep as u can so it lies level with the sand, try get it by its hole.
5) wait until he runs in to get the fish, and they cant get out then.
