Can anyone tell me what the coral in the last picture is? I have had the tank set up for about a month plus it was already established for about 3 years before I got it. If anyone could help I appreciate it.. O I am referring to the big circular one right of the shrimp.... thanks
It's an aiptasia anemone. Search for them, you'll find plenty on this site and otherwise - they are a potentially rapid spreading pest. If you limit the food available for your peppermint shrimp, it might very well turn to the aiptasia for food. There are other methods of elimination, as well.
