For some reason i cant edit my first post so i will post pics of the orange plate here as an update.
Like i mentioned before it is not too happy in my tank not sure why but perhaps because i have two skimmers going and the is not enough food for it in the water column but i can be wrong.
Trying to get the pic but this is all i could come up with.
$20 its about 2.5" inch in diameter.

There is a tiny speck of dirt or algae stuck to the top.
