bit of a stupid question really, but how do you fasten your cables up the side of your vivariums? using tape at the moment but it looks cr*p lol. any advice would be helpful, thanks

which cables? you mean like leads from heat mats/lights? Personally I try to drill holes as close as possible to the electrical unit, whatever it is, so that it doesn't have to go up the sides of the viv. You can use those U-shaped nails if you want, or you can get a pack of those plastic p-shaped clips and screw those in. Maplin > Cable ‘P’ Clips

Oh right, they seem like a good idea. I have just thought of something anyway but i will use these in another instance! Thankyou very much for the advice
