What's my frogspawn doing?

[ChoxRox]

There's a white string coming out of one of the mouths (it's slightly out of focus here). It's just a thin, white strong coming out. Any ideas? Is my frogspawn OK? Also, don't mind the molted shrimp in the back.

I think it's just a feeder tentacle. Mine does that on occasion too.
