My husband has a Aqua One 200 litre saltwater tank with some fish and live rock and did have two anemone's but we are worried that he has just killed them! We bought the tank on eBay and with it we were given Cuprazin along with other bits & pieces.
He noticed about an hour ago that the yellow dye tang had some White spot so used some of this Cuprazin before realising his mistake! Is there anything we can do?! The anemone's are shrinking rapidly
