You can clip the stinger, although I wouldn't worry too much about getting jabbed. It rarely happens.
A drip system is only possible IF you have a drain. You need to drill the tank, with a pipe that runs to the drain (overflow boxes are a flood waiting to happen). Then you gotta tap a water line...the issue with a single tank drip system is heating the water...I've only ever done it in multi-tank systems where the temp is diluted by the volume. I'm sure the folks in the ray section could give you a better plan...
As for legality, the law says
Nothing about the family Daysatidae, to which the FLR belongs...
