Pix & ID: Critters that come in your rocks: the good and the bad.

[DrakeFrst]

It's not the smartest thing I've ever done, but to get rid of the last few of my hitchhiking crabs (the ones so stubborn they wouldn't come out for even fresh water dips) I placed the pieces of LR that I suspected of having crabs into a bucket, then poured club soda through the holes/caves. The crabs got out in a big damn hurry.

It sounds extreme, but I suffered no discernible fallout for my ridiculous actions. I still have plenty of creepies and there was no increase in nitrates (i've never had ammonia). Before going crazy though, you could try an hour or two in a bucket without water with the lights off, or a short fresh water dip to see what you get.

All that being said, the time we spend with our live rock during the cycling process feels like a rite of passage. It's also a lot of fun. Maybe it gets old after you've set up several aquariums, but I think everyone in the hobby should go through those ups and downs at least once


**edit**
Here's the pic of my suspected eunicid - the pic isn't as good as sushi's (thanks so much for posting those!) but I think it's safe to call it a positive ID? Just above where the pics cuts off I have two colonies of Zoas :angryfire:

Hey. It's probably scary to catch him. But it seems to me that it is very tasty. You are very brave. thanks for the information

Just typical sponge growth. No worries.

Any idea what this six-leg star is? I see the legs of these guys sticking out from my rock, this is the first one I've found in my sock.
Good guy, I hope.

Hello!
Can anyone help me with ID this? It came from the sand bed while I'm feeding. The body shows about 4 mm, and the lines near 20 mm extended.

Aiptasia?

Aiptasia?

Hi everyone,

I am brand new to the saltwater tank life. I established the tank with dry live rock. I added a piece of wet live rock in order to add coralline algae to the tank. I saw two of these critters on the rock and did some research and believe they may be Aiptasia?

My question is, do I get rid of them with one of the killing mechanisms or just take the rock out and find another small piece? The rock has only been in there about a week.

Thanks

 

[Crusty1]

Looks like a plant root. Can you send a pic of what is growing around the rock?

Take the rock out and quickly burn the two spots that have the aptasia, and check the rest of the rock for others you don't see. Use a small plumber torch.

Joes juice works well. Other say lemon juice works but I've never tried it.
