I found my perfect little rose BTA decided to end it all last night by jamming himself in the powerhead. It's in my 14g and the water was all cloudy this morning, so I did a 50% water change and started running carbon. Everything else in the tank seemed fine. This is the first time I've ever lost an anemone, but I understand they leave a real mess when they kick it. Should I be OK with what I've done so far or do I need to do anything else?
