I just purchased this pipe organ last week. Seems to be doing great in my tank so far but I noticed a little hitchhiker the day after I got it when I was feeding my tank. It looks like a worm with alternating bands of color (white and purple possibly). I dipped the coral for 10 mins prior to putting it in my tank so whatever it is survived that process. I know not all hitchhikers are bad so hoping someone can help identify this so I know if I need to dip again or not.
