I bought a baseball sized green bubble tip anemone last friday and it had seemed to be doing ok until tonight the only thing I did different was change my pc bulbs the old ones where pretty old, I ran to the store for about an hour and when I came back he was shrivled to the size of a tennis ball and his tenticles went down to the size of angel hair pasta he also is hanging on to the side of a piece of live rock and is sagging down with what looks like a couple of cob webbs hanging off of him. please help me I dont know what to do I shut the lights off already but thats it.... Also my tank is 6 weeks old but I was told my water was ok for an anemone.?
