Salifert Flatworm Exit

[slakker]

Bristle stars will kick the bucket, but also large bristle worms will do something weird...

I don't know what it is, but I noticed about 1/2 dozen monster worms (4-6 inches long) come out of their holes in the rock and puke out grey "ink"... not sure what it is, but none of my livestock died or anything... I just followed the instructions...
