Tony, any other time I would have assumed it was a spawn. But having my squamosa die had me paranoid. Then the gold maxima did this spewing thing, and I though"hmm, maybe it's spawning" but then it died!! So when the blue one started this, I though "s**t, this one's gonna die now". And everyone I know has dying clams, I just panicked...so far it still looks fine.
Not sure what could have trggered any stress as everything has been stable for days previous. Nothing else appeared stressed either. Ohwell, don't look a gift clam in the siphon, or whatever that saying is!!

Thanks everyone for your advice and concern.
