Help with identifying weird thing floating in tank.

I added some critters to clean up my tank. My zebra turbos are hiding under a rock but the other two are finally out. My little crabs have gone MIA too lol. So as i was looking around for them i saw a tiny starfish and this weird 3 legged critter. I'll attach a pic in a second I want to know if this thing is bad should I take it out or let nature take its course!?!?!?

 

Pretty hard to help you without the picture . . . post that bad boy and we'll see what you have in your tank!

 

I agree really hard to guess with out a picture but.....
Brittle star ?


Probly a little different looking any smaller but just a guess by your explanation.

yeah bro!! exactly like that but tinny!!

 

I see asternia stars and mini-brittle stars.

 

Agreed!!!

 

Double ditto

 

So can I assume these guys are safe as long as they are roaming my glass? signs of a healthy tank?

 

Don't worry about the mini Brittle stars they are harmless. In time you could have hundreds in your tank and not notice them. They usually hang in rock and under it. The asterina starfish can be harmfull but I have heard they have been seen eatings some corals (zoas and other polyps) . There seems to be no real evidence of it. They could be just eating dead tissue or dead polyps? I would just keep an eye on it . They also can multiply quite quickly as well.
