Is Aiptasia Possible in Fresh Water?

If you are going to be useing the rock in fresh water then pore some bioling water over the worst infected rock this will kill everything on the rock as nothing will live long in the fresh water anyways.
I did buy some rock a few years ago and 1or 2 pieces had Atapsia on it an a couple did come off in the bucket that the rock was in. I dumped the salt water down the drain and put fresh in it and the atapsia lived for a couple day butthen died. They are resilent little buggers.
If you want everything out of the rock then biol for 1 hr and then rinse a couple of times this will kill everything and remove some of the critters. I would not want all the critters in my rock to be rotting in a fresh water setup.

Not that im trying to get all technical here, but the aiptasia when exposed to the freshwater would actually EXplode rather than IMplode. :P If the water was super-saline (hypertonic) then the cells would lyse (push out all their water to equalize osmotic pressure) and 'implode' or shrivel up. The opposit happens in hypotonic water, the cell fills with water to reduce the osmotic difference and the cell becomes so full of water it explodes.

No, no chance at all of aiptasia living in freshwater! Cheers,

Feels like my first year of University all over again , I don't know about salinity swings but I have watched an Aiptasia survive for over 3 weeks in a sealed small jam jar. Were talking no air, no food and no heat but as they are salt water inverts the fresh water should kill them.

Haha Ohh yeah, they can definitely survive that!

And what year are you in? Haha. I know, its just first year stuff... but its fun, and very interesting
