Allan actually has it backerds......
ac causes an anomaly called tetanic spasms....essentially, if you grab a live ac wire, your hand will spasm around it and it's very difficult to get loose.
dc does not cause tetanic spasms, and will actually knock you away from it. Example: DC welders (most large trailered welders or on site generator/welders) are relatively safe to use in damp locations, the current is pretty well behaved and will normally travel from the stinger to the ground clamp without deviating path. AC welders, on the other hand, will bite you in the butt in damp conditions, the current will seek the path of least resistance in the presence of moisture, and will routinely knock your socks off.
Either way, you got shocked, not electrocuted. And since these were leds, depending on the power adapter, you may not have even gotten a full jolt of 110. It's not surprising that you got out of the tank, since you weren't holding onto the source of power when it happened.
The thing to remember, it's not the voltage that will kill you, it's the amperage. As little as 20 MILLIamps (that's 0.020 amps) can stop the heart.
I'll be the first to admit, getting hit with 110vac will make you cuss, and there's a very remote chance it might kill you. It's not a fun experience, no matter what.
