So this guy showed up In my qt tank with my new diamond gobi! I did fill the qt from my display tank so it could have came from there.

[femritet]

I think aptasia I m pretty sure I can see its foot. And they're very mobile critters.

 

[femritet]

It totally could be aptasia, I’ve junt never seen one that small before! It has disappeared, so I’ll keep my eye out and see if I can find it again

I've had that before, don't think it's aptasia but I think it's not good to have.
