I'm with you on the whole yuck thing I have been living in this apartment for about 7 years and never had this problem. The second one was in already I just couldn't see it since it was on the high edge of the tank I saw it fall when I nudged the tank. Only part of my tank is completely secure since I don't have enough clamps. even so I feel the double sided tape will not allow bugs of any kind to get into the tank which means I will go out and buy some tomorrow morning.
