Hi- I am a new hobbyist and am just cycling my first reef tank! I went to my LFS to purchase my live rock, and noticed some interesting hitchhikers. I have done some research and believe one is an Aiptasia anemone- and have read it is recommended to nip those in the bud. But don’t know what the rest of these are? And if they are good or bad?

After a rousing round of Google searching and searching these threads, I thought it best to ask the community for help so I start my tank off as best as possible and avoid any unwanted pests.

We have photos of:
1. Worm like growths- 1 pink and 2 green
2. White soft-bodied sponge or coral? It opens/closes
3. Green-ish grassy-like structures (located only on left side)
4. Finger like structure that looks “squishy” in appearance- I think this one is Aiptasia?
5. Round white domes that looks like they have smaller little balls inside- don’t have fuzzy appearance


Thanks

1. SMall vermitid worm species. I never worry about them myself but if they bother you you can use a syringe with a small needle and H2O2 and inject it to kill the worm inside.
2. Looks like a Pinapple Sponge, beneficial.
3. Looks like small colony of a species of tiny featherduster worm.
4. Yup, aiptasia. I use a syringe with a small needle and superglue gel to kill them, it's messy though.
5. Tethis sponges, beneficial.

All the yellow sponges you see on the rock are very beneficial cryptic sponges and remove and recycle labile DOC. Here's some videos you may find informative:

Thank you so much for your reply, and for all the informative videos. I will be taking care of the aiptasia before it gets out of control.
