gingerbeer Posted August 20, 2016 Report Share Posted August 20, 2016 Apparently I have a starfish. I did not know until he showed his 'face' this morning. He is only very small, maybe 8mm across. Is he good or bad? How can you tell? Link to comment Share on other sites More sharing options...

ageofaquariums Posted November 16, 2016 Report Share Posted November 16, 2016 Looks a bit predatory.... like a young Patiriella or Petricia species. You can tell when they are feeding on something as they puke their guts ontop of it. Link to comment Share on other sites More sharing options...
liquidg Posted November 16, 2016 Report Share Posted November 16, 2016 I agree, that shape means no good usually. To be sure there are only three to trust completly, they are smooth surface brittles, biscuit sea stars and feather sea stars, any others and its good luck!
