not all zoos have palytoxin. I believe they only get them when they are exposed to a diet of a certain diatom. Stings from nematocysts are best dealt with by soaking in vinegar as it deactivates the nematocysts; urine only makes them fire more. If you don't have vinegar, just rinse in saltwater.
To me, the least regarded yet likely most serious of all aquarium dangers is the microscopic kind. people tend to ignore the viral and bacterial nasties like vibrio and mycobacterium (yes, a derivative of tuberculosis). in fact, marine biologists have recently found that viruses and bacteria make up a much larger portion of the ocean's biomasss than what was originally thuoght; possibly greater than half the biomass in the entire ocean! infections from the likes of these have led to aquarists having to get their fingers amputated. NEVER immerse an open cut in your tank unless you're wearing gloves and always rinse in warm soap and water afterwards.
