Fish and maybe a coral?

[OceanTeacher]

Hi all! I inherited an aquarium earlier this year, and have been taking care of it without really knowing what's going on. I'm trying to learn, and I figure identifying my creatures is a good place to start.
I have 5 fish. I know one is a clownfish, and I think another one is a damselfish?

Sorry the pictures are a bit blurry. I only had a phone camera.
I also have something I think might be coral:

Any help identifying them would be really helpful!
(I already know that the anemone is Aiptasia, and that I also have an algae problem. I'm working on getting rid of both, but if you have any advice for me about that, I'll take that, too!)

Those brown things your seeing are Protopalythoas I believe.

Thanks! This is really helpful. Reading about the species, I'm recognizing lots of the behaviors of my fish; the striped damselfish hides a lot, the domino damselfish attacks my cleaning things, and the green chromis is usually at the top of the tank! Cool!
And protopalythoas sound interesting. The article mentioned they are toxic; should I be cautious when cleaning the tank, or only when handling them directly?

Only when handling them .
