Take this with a grain of salt as I am NOT a doctor.
Someone being alergic to a bee's sting is just that, an alergy. You could be alergic to dogs but not cats. BUT, What your alergic to in a bee's sting is the venom that stinger carries. I would be willing to bet that someone alergic to that vemon would have a propensity to be alergic to other mild stinging venoms, but as in the dog vs cat example, its not guarunteed.
As a simple precaution, if you're stung by anything in your tank I would at a minimum take some benedril and be aware of your ... "self", for lack of a better term. If you begin to flush, heart rate increases, or feel any sort of ache travel from where you were stung, seek help. When seeking help, try to be as descriptive as possible of what exactly stung you. This is what I did the first time I got skewered by my sea urchin... man, talk about burn! and that venom left a nasty black dot in my hand for a few days... but no ill effects, just irritation. Now had my wife gotten poke by the urchin, i likely would have been taking her to the hospital (she's very alergic to stinging insects)
hmmm should do some googling on this... see what we can come up with.
