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,
Chris
