What is this species that appeared in my tank?

[ClownfishLouise]

What is this thing? I just noticed it. I only have 2 clown fish and 5 hermit crabs in my 23 gallon tank. I definitely didn’t add this. What is it?

Looks like Aiptasia. May have come on rock or on a hermit crab shell when small

Yep, here’s what happened to a friend of mine when he had some issues that left him unable to maintain his tank for a while. The Aiptasia took over.

Aptasia out of control

What would you guys do about 100s or 1000s of aptasia.

Small one like that, I would just suck it out with my next water change. Scrape the glass where it's connected with the hose intake as it's sucking water and it will come right off. Some sand will go with it too. Don't do it half way - make sure the whole thing goes up the tube.

Looks like Aiptasia, I guess. This activity is one of my hobbies, but it's not my only one. Gaming is another passion of mine, and I found great help with tips and hints here
