I need some ideas on how to keep an aquarium lid down.. Im afraid my baby pastel will get out.. ive been looking at zoo med's lid locks but they are $18 for a couple cheap plastic clips...

It is a 10 gallon aquarium..i was thinking small bungees on all the corners but girl friend said no that would look bad... and the couple heavy books on top just ain't cutting it

Any Ideas ladies and gentlemen????
