Ok hot glue it is. The power cord for the Kane mat and probe for thermometer will run through a hole drilled in vision tank and will be under substrate so he won't be able to be tangled in it. Right now I have the probe for thermometer running from middle of hot spot to the closest edge then running around the edge to the corner of the glass door all under substrate and he hasn't been tangled yet so I should be ok. I have the hydrometer probe running through the top corner of screen taped along the side and top but it doesn't look that great so I'll be drilling holes for all of it and plugging holes so it looks clean. Just have to wait for my v400. Hopefully it doesn't take the 2-4 weeks vision says it takes.
