Cleaner Wrasse Goo

[paultn]

i bought a cleaner wrasse yesturday, and after being bullied by a ytb for a bit, it decided to go spend the rest of the day and night hiding in a barnacle. i woke up this morning, wrasse is happily swimming about, but in the barnacle there is, what looks like a sack of goo. its see through, i was unable to get a decent picture of it, does anyone here know what it is??
thanks, paultn

The wrasse spins and sleeps in a cocoon at night, this helps it evade night time predators.

My 'goo sack' worried me for ages until I spotted my Wrasse spinning one!

Yup, that's what they do. Interesting isn't it!?

So much better than boring old tropicals!!
