Fish Tank Divider Problem

[plmike]

So I bought one of those 22-55 gallon tank dividers at Petsmart..Its about 1cm too small on each side and my small Severums keep escaping to the other side. Any idea on how i can keep that from happening. Thanks

i think people have used foam with the eggcrate type dividers on the edges to hold it snug against the glass. haven't seen your style divider but it might work for you.
