nudibranch in my Zoos--safe?
 

I recently purchased Zoo rock and I noticed some nudibranches living among the button polys.

These creatures take almost the same shape and colour as the zoos.
They've got spikes on their back which resembles the edges of button polyps and about 1/2 a cm in length.

Just wondering are they symbiotic or are they eating my zoos?
take them out?

thanks

Just don't squish it with your finger :eek: Wasn't there a thread on RC about some guy who did that and almost died ?

I had what sounds like the same nudi's come in on some zo's.I removed a couple and decided to leave the rest. for a few months they spread every where, nothing seemed to be disappearing so I just ignored them. Come to think of it I haven't seen one in ages.

ok I guess I will leave them in my tank until they start making some troubles. Thanks for the info.

These guys are kinda pretty, and I noticed that they change colour depending on the surrounding. From yellow to brown, to the same colour as my button polyps. Kinda neat.

Take some pictures. Nudibranchs' don't typically live very long.
