Carpet Anemone 

-live on coral reefs and like to hide in the crevices or under rock just like many other anemones
-they usually range throughout Indo-Pacific Ocean and size to be about 3ft long
-their nutrients is made by algae, which lives inside their tissue and produce sugar and protein for the anemone to stay healthy
-live 100 years+
- one of these anemones may host many types of anemone fishes
-they reproduce slower than other anemones, which causes them to over collect and sadly, that threatens their survival in the wilderness under the sea
-they are actually collected for pet trade throughout the years because of this
