simon2629 Posted January 8, 2020 Share Posted January 8, 2020 Hi, Guys I've swap all my stock from my old 20gallon tank to a new Innovative Marine 20 galling AIO tank. New live sand, put 50% water from old thank and topped with new salt water. Everything looked good, coral open, but second morning I found all my zoos on one rock are disappeared! about 15 heads of them all gone! like never exist! Help! Anyone know why? Quote Link to comment
Clown79 Posted January 8, 2020 Share Posted January 8, 2020 Did you check your parameters after the transfer to ensure everything matched? Any chance the rock was placed wrong in the tank and they are on the other side? Quote Link to comment
simon2629 Posted January 8, 2020 Author Share Posted January 8, 2020 The parameters are all good, and I took the rock out and checked around. They just gone..... Quote Link to comment
StanD Posted January 8, 2020 Share Posted January 8, 2020 Do you have any fish in the tank? Crabs? Quote Link to comment
simon2629 Posted January 9, 2020 Author Share Posted January 9, 2020 Just 2 clown fish, several hermit crab and 1 small emerald crab Quote Link to comment
Clown79 Posted January 9, 2020 Share Posted January 9, 2020 Were they growing on the rock or glued on? I've had ones I glued on that got removed and found floating around the tank. Quote Link to comment
EthanPhillyCheesesteak Posted January 9, 2020 Share Posted January 9, 2020 This really sounds like you have some type of pest. Zoas just don’t disappear, they are pretty hardy. Something ate them or attacked them. You need to check everything in the tank for pests. Wait and watch the tank while the lights are off, if it’s a nocturnal predator, you should see it then. Where did you get your live rock? Quote Link to comment

I got live rock from local reef shop, and been in my old tank for 6 month and never seen any problem, it just happen over night, kind scared me... Quote Link to comment

Well that’s weird. I would suspect a pest, but maybe not. If all other corals are ok and params are fine, I really don’t think that they can just disappear without some kinda pest Quote Link to comment

EthanPhillyCheesesteak Posted January 9, 2020 Share Posted January 9, 2020 Did you check the tuxedo urchin? They sometimes pick stuff up that they aren’t supposed to?😂. The emerald could always be a possibility. Crabs sometimes get appetites for coral Quote Link to comment
