Looking for small aquarium divider

[Mpwallace1]

Hi I bought a 10 gallon hospital/ quarantine tank along with a glass top, and I'm looking for an aquarium divider that will accommodate the glass lid. It's small but it's only for those small freshwater fish like neons and the sort.
The only ones I have seen at Big Al's and online are ones that hang from the edge of the tank, which will interfere with the glass top lying flat along the top edge.
Has anybody seen any other divider that doesn't utilize this hanging method, but it is accomplished by some other design?
Perhaps spring loaded that pushes against the interior walls or something along those lines?
Thanks.
