Opening in the back of my tank

[Vipex23]

Because of the filter and the wires from the heater in the tank, there is an opening at the back of my tank and I'm worried that some of my fish could jump out at some point. What would you recommend I use to cover it up that won't make the tank look bad? Do they sell something? Thanks.

duct tape, masking tape, scotch tape...
black bristol board.. black construction paper... tinfoil...

try screen from an old window or a piece of panty hose---seriously. That would work good.

make sure you use a nice sticky tape like somonas suggested, so when the fish do jump, they get stuck there hanging in the air lol

i would use plexi glass myself, but remember you want some gas exchange so dont cover up the tank 100%
