Umm, that's a pretty dangerous situation
Let's just say it's a good thing you only got shocked
For the sake of your critters, I'd suggest you unplug the ground probe for now and DON'T TOUCH the water
This will cut down on the amount of current in the tank and give them a break
DO NOT touch the water without the probe in place as you will become the ground

Maybe spend tonight reading up on aquariums with GFCIs and ground probes

1 - Plug the probe back in when you have the meter ready to go
2 - Find the hardware issue and fix it
3 - Install a GFCI, or a bunch of individual ones for each 'wet' hardware piece
