There is this white, stringy stuff coming from my frogspawn. It only appears towards the evening, after the daylight bulbs have gone out. It appeared last night too. Is the coral expelling waste? Or is it expelling the bacteria(?) that makes food? Here are some pics, sorry for the bad quality. I will try to get some better ones once my camera battery charges. Also, it does not appear to be coming from the mouth, but from the tentacles.
