Another surprise inhabitant

[sbertomen]

Now look what I found in my tank. I first saw it riding on a hermit crab, now it attached in clown country so I am not sure how long it will survive.

Looks like a small starfish. They will typically multiply like crazy. They break off pieces of their legs that grow into new starfish. I always see them on my glass eating the coraline.

 

[sbertomen]

Oh oh - multiply like crazy does not bode well for a little 20g.

 

[Ken668]

Well, maybe crazy is an overstatement. You can always pluck a couple here and there to control the population.

Those are White Pillow Stars. They can be bivalve munchers, occasionaly eat encrusting corals like GSP. Just keep an eye on it. they rarely get bigger than a quarter in any of my tanks.

Whenever I see one in my tank, I pull it out. The eat coraline.
