Can someone ID these for me please.

Came in on a huge colony of leather I purchased.

Well, the polyp on the top left of the photo is a species of Rhodactis mushroom, the other ones are Aptasia anemones, and can become a problem if you have enough particulates in your system.

Aptasia.... looks like there's another small one behind. get some peppermint shrim ASAP before it become a problem.

 

[Mr Bowfront]

I have two peppermint shrimp and there use to be 5 on that rock only 3 now. I think I'm on the right track. They are on my radar now and will be watched carefully. Only 6 months in right now this is my first aptasia experience. The struggle is real!!

Aptasia. Try to take it out asap. I usually have to glue over it if I can't pull it out manually
