Day after HARLEQUIN Shrimp added
[ ( ASTERIA STARFISH ) on the RUN !! ] Weird
This is something I've never seen before.
Sure the Asterina Starfish would climb on the Glass, in flow areas, and usually at Night.
Today, the day after the Harlequin Shrimp was added, there were Tons of Asterina Starfish, up high on the glass (During Lights on). Like they sensed the Harlequin Shrimp Hunting them.
What is even more odd to support this theory, is lot of new Asterinia's, and they are very white colored versions of them. Possibly they were in darkness in the rockscape and didn't accumilate pigment. DId the Harlequin scare them out?
I wonder if the Starfish actually talk Chemical Signals to warn each other of a predator.
Same thing happened to me the last time i added an harlequin.
on a side note: not sure it was related but after a while, when the asterina population was barely visible i end up with a lot of worms on the scape.
The kind that build calcarous tube, it was becoming painful to handle the rocks.
My theory is either the asterina were doing predation on them or they now had more food available.
Not sure.
