Most of the times I've had a GFCI trip, I've been able to find the cause. This is just one of the few for which I'm not able to find a cause. I've had about 4 or 5 like this in as many years. I'll go with current overload as a likely culprit as because it happened just after the lights turned on. The only thing is that it should not be anywhere near the 15A limit.
Moreso my lesson learned though here is that I would prefer an alarm of some sort for the future. Indeed - the GFCI tripping tells us "something" but that is not the real root of the problem - the problem is that "stuff happens", and when it happens when you're in a position where you can only assume that things are OK - then it would be nice to be notified somehow.
Cube tank with the ritteri and its inhabitants appear to be OK today. Other than now being a fishless tank, the 20g appears OK too. Snails, abalone, etc. - everything but the fish - weathered the flatline just fine.
Doesn't compare to a total tank loss but I'm just sad today anyhow..
