That depends on how big your tank is and how big the anemone is/was. Like anything that dies, there is an amount of toxins and amonia that release. Unfortunatly anemonies seem to decay much faster than fish and there are no critters that like to eat them. I curious though, in a week or 2 have you tested your water chemistry. If in fact you were concerned an amonia test or at best a nitrate test might be able to shed some light. If nothing shows, then even if it has passed, there is nothing more to worry about.
