    Are these copeods ?

    Hello everyone, I have these very small white things on my glass that are moving around every few seconds. My clownfish seem to be eating some of them. I can't get any clear pictures but I do notice that they have really small antennas on their head.

    Are these bugs?

    Anyone know what these tiny bug/shrimp looking things are? They are all over this rock and under the coral. Are they good for the tank or are they about to kill everything in sight? Thank you!

    Foe?

    I have heard everything from pistol shrimp babies to bad isopods. To good film algea eating isopods. Can someone help me ID these please. If you zoom in it looks like mandibles on the big front end. I disturbed the back chamber of my AIO and these are now all over my display. Thanks!

    Nassarius-like snail ID

    Could you please help me id this snail? It was caught off the turkish coast of the mediterranean sea. It seems to be a scavanger, they all gathered around a dead molly or meat but they don't seem to eat any algae. They are very inactive and somewhat nocturnal i guess. Sometimes they randomly...

    Friends or pest?

    Found this little guy wandering my tank glass this morning when putting up some new frag racks for some coral I had coming in. He/she was not one of our purchased cleanup crew. Did our clean up crew multiply or possibly a stomatella snail? Or is it something else that should probably be tossed...

    Is this aiptasia? Got some new zoas and noticed this..

    I had a friend that is getting a new tank, so had to get rid of a lot of his corals. Some of his zoas have feather dusters, which I’ve heard are healthy for a mature tank. These pink cat eyes are the only corals that have these. They’ve been in my tank for about a week and have now popped up...
