Anemone and clown fish are symbiotic. It means that the fish is protected among the tentacles which are poisonous. And the fish chase off other fish who come round to annoy the anemone. Eat the fish I say. Then eat the anemone. It doesn’t work that way. The poison rubs off on the clown fish. So fish and anemone are symbiotic. Get it? The pictures show the mouth of the anemone? I don’t know.
Anyway it is usually not covered in gooey gel. This was odd. No one could tell me about the gel either. Some things you observe and then make up explanations in your mind. It’s kind of like religion. Nope, strike that. This is not a political blog.
