What are these!? They are multiplying...

[smrf010]

I have had my tank set up for about 4 years. I usually just add water and the tank just keeps maturing without any issues. My fish are extremely healthy but these brown anemone looking things keep multiplying and it is beginning to look pretty bad. I would really appreciate if someone could tell me what these are and how to remove some or all of them. Thanks Alot. Heres a pic...

Aiptasia

Get a syringe and Kalk Paste and plaster over their hole that they're in. Turn your pumps off while you do.

You can also try lime juice,l emon juice, boiling water, joes juice, peppermint shrimp.

Here are a couple websites that talk about Aipstasia and how to rid your tank of them.

If they are small, peppermint shrimps can deal with them, it worked for me at least, but for the larger ones I had to kill them by using joes juice and by pulling out any rocks that could be pulled out and scraping them/salting them. But after I cleared the big ones I noticed that all the smaller ones were gone too so I assume the peppermint got them and any others that have popped up because i haven't seen any since.

After reading these links I think that injecting them with lime or kalkwasser would be best. But I have another question, if I do this will I need to do water changes and by how much percent?

Also, when I inject them do I have to physically remove them or will they die and stay in the tank?

As long as there are no corals on those rocks (doesnt look like it), you can just bury the rock under the sand for a couple weeks, that will kill them just as well.

[smrf010]

Yeah its just LR, but I have them on my glass as well, a couple. I would prefer not to flip them or bury them, I have a couple fish whos hideouts are in certian areas of the rock. Does Kalkwasser harm the fish or will I need to perform water changes if I decide to inject them?

[gsxunv04]

wow, thats what you call a textbook aiptasia outbreak, it may be time to trade some rock, all of it! if you decide to kill them i would advise lemon juice, a syringe, and a dental pick, and hemostats.

[mickyfin]

with this quantity don't use Kalk paste, it will ruin your water quality.

Use Joe's Juice.

if you have no corals attach to that rock take it out and deal with it outside your tank then put it back when you finish. Don't worry about your fish it will find another place to hide.
