Hey guys, just recently started a 5g fluval all in one.(first saltwater attempt) it’s been running for nearly a month and a half. I’ve got this torch coral that was doing great for a while then started acting weird. Just not fully extending some polyps shrinking and becoming fat and stubby. I noticed a hitchhiker and I don’t know if it’s a feather duster or what. And I don’t know if I should just leave it or remove it. I dipped the torch and acclimated before placing it in my tank as well.
