Pascal Posted August 3, 2020 Share Posted August 3, 2020 Hi, i have a strange issue with my Zoanthids. The colony has been in the tank for a year and was very happy. I went on holidays for 5 days and came back to 4 holes left where large Zoas were. See photo. I can’t find them in the tank, it’s like they disappeared or been eaten. I had the same low stock of fish and crabs for the past year and only added a chalk goby. I tested the water and all parameters were fine apart from KH that dropped to 6. I addressed this immediately and it is now 9.8. i have never seen holes like this. I can’t see pox or aptasia. I have a small feather duster that grew itself near the holes but it’s been there for 6 months or so. What could it be?? Thanks Quote Link to comment
