What in the .... are these things?!

[Dylan7huskies]

I noticed these two little bug like creatures in my tank a while ago. They move.... any ideas?!

 

[ConorBishop]

No idea :S Iv always been in the mindset of ‘when in doubt, take it out’ have you got a refugium?

 

[murphy357]

Can’t really tell from your pictures, but could they be Chitons?

They're shaped like flat worms but the coloration is odd...

Im thinking isopod maybe in the Sphaeromatidae family.

Maybe! Are these bad?!

Isopod which can get huge. A large melanurus wrasse may attack and feed in these

Not the ones in that family. But there are others who make a meal out of your fish.

Not to dismiss the isopod theory......

I do see a little bit of a resemblance to a nudibranch.

they look the most like the Sphaeromatidaes
