We came back from a short stint away to find our usually large anemone looking extremely deflated and sick. No idea what might have been the issue. We did recently cover the tank and saw an increase in algae across the board so our first thought was that it was getting too warm inside the tank so we took off the cover. That night the anemone seemed to come back to life and look great to which we left it to run through the daily lighting cycle. We returned that afternoon to see him deflated again and looking close to dead. We immediately turn off the lights and he has inflated a bit but not to full stature. We also removed our heater as we thought this may have been malfunctioning causing a heating issue. He is now in sort of a half inflated state and still not looking well. His mouth also looks a bit chewed up. The pictures dont do our concern justice but any ideas from that scenario might help. Thanks for reading.
