So I'm not building my own set up, but I figured this would be the best place to ask about fixing a tank. I bought a used 55 gallon tank. The people had been using it as a reptile tank. Well I didn't realize until I got it home, they had ripped the plastic crossbar on the top out. I assume to accommodate 2 mesh tops for using as a terrarium. So without that cross bar, there is nothing for my 2 hoods to sit on in the middle. Does anyone have any ideas about how to fix this?
