i still think the goby dies first

Yeah, he will blow faster than a Christmas light fuse...

Yellow watchman gobies? I doubt it. Those suckers are iron nails tough unless they get an infection from injury. A lot of wild caught ones come in torn to shreds from the pump gun they use to catch them and heal up just fine.

Green - just install a GFCI and ground probe. You'll be fine then!

That is correct, if you have a resistor connected to both ends of a battery you have current flowing. But, just because you have voltage does not mean you have current flowing. Take out the resistor and leave the gap in the wire where it was. Read the voltage at both wire ends, you will read a voltage, but no longer have current flowing.

So this is exactly the question we r discussing, no one said it was a huge current just that it was there if you grounded it. Does 37 micro amps affect the health of your tank more than a 30 ish volt potential difference ungrounded. That's the question. And you can have an induced voltage and transformation works via the phenomenon call induction. The resistance of anything is never zero as said. Every spinning or powered object injects a stray voltage/current that all add at some frequency and phase to result in some induced ac. When grounded the induced current is minimal but it is there. You cannot wholly seperate a v and I they are inherently tied together as the r is typically fixed they are both a linear function of one another. I don't know that any of us are really doing anything but arguing semantics. The real question is simply does Microamps of current do more danger than some 30ish volt potential difference.

I should've just let it die I have a bad habit or talking/arguing things to death. Do it or dont the world will continue to turn

Ha!!!! I do that sometimes too. The funny thing is, the only thing that was really ever agreed upon was that a GFcI is always a good idea around water. As for the ground probe, well, that can still be debated. I think things ended up a little off topic.

Sorry, but you can not draw power from induced voltage. You can draw power from induced current, though, IF the current is alternating. That current has to be starting and stopping. It then builds and kills a magnetic field, It is building and killing the magnetic field that causes current to flow in that near by device that is "drawing power" from the other source of current. Voltage doesn't do work nor flow. Current does work and flows. Current produces magnetic energy and magnetic energy produces current. Receiving power from a near by current source is called transformation, and is how transformers work. You can transform AC electricity and can not transform steady flowing DC electricity. Volts do no harm and do no work. Current harms and does work for us. The last time you pulled scotch tape off the dispenser you most like reached over a 20,000 volts potential in your body... and you never knew it because it did no harm. And no that is not a different kind of electricity.

Exactly!!!!!

This is the best advice! Also, Mike's pickle presentation at the meeting earlier this year helped me make my decision.....which saved me from a shocking experience last week.

I came home from work one day last week and found one of our blue leg hermits in the return section of my sump. I do have strainers on the pump input pipe, but I quickly reacted and went in for the crab. My elbow knocked one of my cpr fuge lights into the water while my hand was fishing out the crab. Deep inhale and gasp - everything shut off immediately and I felt no shock whatsoever. After a few explitives and moments of feeling like a dumb butt I dried off my arm and removed the fixture. I reset the GFCI and everything came back to life. Then I looked up to the ground probe that I put in and thought about the pickle which could have been my arm. Thanks to this forum, and the folks on here for passing along this valuable information.

After a few days of drying out, even the compact flourescent fixture came back to life. I'm sold on having a GFCI and ground probe.
