As far as wires (i hate them lol) I use Silicone on my 40 gal long for the Thermometer wires & Probe. I also wrap the wire in electric tape (only about 1" of it) where it gets pinched under the screen frame so it doesnt cut the wire insulation agter a while.
I use Silicone to glue the Probe to floor under the substrate (i use butcher paper) above the UTH in the Hot Hide. I also spot Glue with Silicone the wire in a couple places for extra security and then apply A LOT in the corner of the tank and use my finger to completely go over the wire all the way up to the Lid in the back corner.
This has kept my snake from getting all wrapped up in the wires since I did it. Drives me crazy hahahhaa
Glue the probe inside, right on the glass? On top of the uth where the snake stays? Wont that melt the silicone? (We are talking about a hot glue gun right?)
