I got one much like the one you have there. Is there a good way to keep the cords out of the way? I tried burying them in the substrate, my little one still manages to drag them around. I don't want to use tape in the even he could get stuck.
I know a lot of people use super glue... Otherwise try placing a heavy piece of cage furniture (a rock hide or something) on the part of the wire just before the probe.
