I have a 180g acrylic tank. I will have a fully grown oscar in it. The top of the tank has 2 square holes roughly 22" x 22". There are no grooves to sit tops in so they are secure. I'm worried the oscar could hit the tops and knock them in. Which can be dangerous if they are glass and break.
How have you secured the tops to your tank? What can be used instead of glass?
Sorry not the best pic of the top of the tank but that should help.
