Hello everybody I just found this little white 7 legged starfish in my tank, from what I could tell from looking it up on the internet, it is a asterina starfish, some sites said they were no problem and some said they were, I don't know where it came from as I have not added anything to my tank in months, besides what I got from Jacob at the last meeting. I was just wondering if anyone else has these or has any info on them that could maybe help me decide whether or not I should leave it in my tank
