lol Mine tries that too, but I moved everything just far enough away from the glass that she don't get stuck... Still working slowly on the new sett up, what if i silicone the background on n seal it so that its impossible to get in behind it? It looks little odd outside the tank... The top screen has been 'fixeed' so that there are no holes for wires n is secure... even if she could climb to the top she couldn't wedge herself in it or get out (tested by me pushing it up it don't budge) Holes are all hot glued shut n solid...
