Newbie with live rocks found some living things

Just got 30lb of live rocks from this store (not Petco), the rocks looked cleaned and didn't smell anything bad but as I put them in next day I found some interesting organisms moving around. First time I am seeing this so hope you can help me whether it is good or bad.

Tank is empty, still cycling without any fish on its first week.

ANy help greatly appreciated.

 

first off, welcome to 3reef!

and for your questions, the first pic is an aiptasia and the second is a bristle worm.

i wouldnt worry about the worm but the aiptaisa need to be killed. try injecting boiling hot water into its mouth. or other chemicals that you can buy at the fish store

edit: oh and dont put a peppermint shrimp in there during the cycle. although they do help rid the pest

 

Yeah after looking online I found it was a aiptasia and also found ways of killing it with lemon. I'll try that and see how it goes.

Thanks a lot ~

 

If your ammonia is still building in your cycle chances are that aptasia will die off on its own – as will with worm. Boiling water in a syringe works well – a little reef glue over his hole will make a nice sarcophagus for his eternal slumber as well.

 

Lemon juice worked for me.

 

Welcome to 3 reef Yojen

aiptasia can be a real pain ,
there are 2 commercial products that are also known to be effective
Joes Juice and Aiptasia X
in addition to injecting with Lemon juice, Vinegar or boiling water
