Hi please some advice if possible, my bubble tip anemone, which is about 30cm in diameter has been fine for about 3 weeks, have recently added a yellow tailed clown which has hosted the anemone straight away which i thought was great, he has been feeding it and everything. But in the last hour the anemone has completely collapsed in on itself and spat out about 2 days of the clowns food, now the anemone looks like it is dead, any help please.
