What is this growing on my live rock?

  • We are currently upgrading MFK. thanks! -neo
They are aptaisa. The best way to get rid of them is Peppermint Shrimp, and make sure they are Peppermint Shrimp. Don't try and clean them by hand or you will damage them and many more will grow. It will take awhile but the Peppermint Shrimp think they taste great.
 
If it's aiptasia they'll grow pretty quickly and you'll be able to tell for sure. Give it about a week, they grow like weeds. Once they're a little larger you'll know for sure. If they are aiptasia, Blue Vet makes stuff called Aiptasia Control. It's a milky liquid you squirt on them with your pumps off, they melt right away and it's reef safe, won't hurt your soft corals. Really cheap too, I used it in my nano when I got some aiptasia (i have a coral banded shrimp and he won't eat aiptasia but will eat other shrimp), works great.
 
i have had this in my tank for over a week now and they havent gotten any bigger, there arent more patches of them around my tank just in the one area. its not an area that i added any live rock too recently, maybe two months ago. could it have taken that long for them to get to this stage of their life and finally start showing?
 
Sounds like a coral for sure then. Aiptasia can literally sprout up over night, they grow pretty fast.

I bought some live rock once that didn't have anything attached to it. Took 2 months for some xenia to start showing up out of no where. So to answer your question, yes, I believe it could have taken that long for them to start showing up. Water parameters regulate it somewhat also.
 
this stuff did seem to sprout up overnight, but then again i didnt really look for it until i read this post so later on at night when i got home i was down looking closely in my tank and these things were in there. not to the extremity of the pictures in here by any means. just like two little patches of them and a few on the back glass of the aquarium. i definitely keep up on my parameters. weekly water changes of 15-20%, my nitrates stay kind of high though because i have them out of the tap. looking into getting an RO or RO/DI filter so i can stop this. everything else is good though, 0 nitrites, 0 ammonia, ph is at like 8 or 8.2. it would be devastating for me to lose my green spotted puffers so i keep up on the maintenance. had them for like 8 months and did the fresh-brackish-marine conversion with them and they are still going strong and growing. some of the most awesome fish i have ever kept

jellies would be awesome :) :) but i would only want to keep like 1 or 2

He didnt mean actual jellyfish...its a polyp.

isnt this what they decided this guy had in his tank? read it, doesnt it say that the moon jellyfish polyps once they mature will break off and become jellies and then go through metamorphasis to develop the oral arms that hang from the disc of the jelly. but for this polyp to mature and thrive and eventually break off into jellies do i need any special lighting? they seem to have started to grow without a problem with the lighting i currently have, which is just a regular tube light that is not made for corals and probably wouldnt be sufficient for any corals.
