How fast does aiptasia grow?

[Son Of Skyline]

I scraped off a small aiptasia on my clam last week and now I have the clam in a quarantine tank. How long does it normally take for aiptasia to grow back noticably? I'd like to put my clam back into the main tank but I want to make sure that I got all of it before I do so. My main tank is free and clear of pests and I want to keep it that way! Thanks in advance [img]smile.gif[/img]
