Perhaps 'Sea Urchin' and and 'Sea Anemone'?
I think a sea anenome and a sea urchin can live together because i have a little aquarium and there is a sea urchin and and a sea anenome (if that's how you spell it) living in there and they were perfectly fine. BUT if you have a sea urchin do not have any crabs in there, because my sea urchin killed one, and almost killed another one by taking its claw off. :(
Sea weed, green algae, sea sponges, sea urchin, sea anemone, kelp, sea grass, phytoplankton.
is the relationship between the clown fish and sea anemone
COMMENSALISM as the crab benefits as the sea anemone provides it with protection but the sea anemone doesn't benefits nor is harmed by the crab
The anemone will protect a clownfish, the only fish that the anemone will not sting.
