What the...???

[BadPhish]

I came home from work today to see that my otherwise healthy zoa colony appears to be puking tenticles...really...that's what it looks like. About half the colony has light brown stringyness coming out of their mouths! I'm not particularly worried because nothing else seems wrong but I'm a little stumped as to what the heck is happening. I did turkey baste some mysis on it yesterday while I was doing some spot feeding to see what it would do...but I did the same with another colony that looks perfectly normal today. Has anyone else seen this happen before?
