A GFCI will not trip if both the Hot and Neutral wires are exposed to the water at the same time ie; the seal on the heater let go and flooded the tube.
If you have a GFCI and a proper ground probe, the GFCI will trip.

FYI, without the ground probe, and both wires being exposed to water, you could have gotten a serious or even deadly shock if you touched the water.

Same can go for those of you out there with ground probes and no GFCI.
An exposed wire in the tank can flow back through the probe, possibly without issue, but you put your hands in there and tada, Christmas Tree. Especially if it's the Hot that's exposed.

Final thought;
Don't put all your equipment on one GFCI, unless you don't mind everything being tripped at the same time
