C&M and EAS - Can Cockroaches Really Kill Small Fish?

Dr Chris asked if we could use clownfish stingers to protect ourselves from being stung by jellyfish. Dr David said the idea is a great one but there are some problems with it. He says people wouldn't cover themselves in anemone snott and you'd still get stung by a jellyfish anyway so I don't think that's going to work. The doctor also revealed he got stung by eerocangy, a kind of box jellyfish which can be lethal.
