I'm looking for any tips on making a new hood for my fish tank . It's a 35 gallon diamond shaped corner tank. I plan to make it out of plexiglass. It's going to be planted with only a few small fish. So I don't need a place for a filter . All I'll need is a small hole for air and Co2 lines and heater cord. I'm also thinking that I can use the odd corner I cut off of the square sheet of Plexiglas,to make it diamond shaped, to make a hinged cover for the feeding hole .
