We bought the anenome from a person that sells frags from their home. Our tank has been set up and running approximately 1 year. We have 2 clowns, an emerald crab, a porcelain crab, a goby,and a starfish. We also have a mushroom, toad stool, and zoa. Our water parameters were perfect until we put the anenome in and saw problems. Everything is still perfect except nitrites and they went off the chart. Doing a water change today. Luckily we quarantined the anemone before it could harm or kill anything else. It's a 55 gallon tank. Which we are upgrading to a 90 so nothing else will be introduced until new set up is complete.
