I just set up a 55g community with an over flow and I am having a heck of a time keeping fish out of the over flow, I don't want to shut down the tank and Silicon somethingto the over flow, What else can I do, I have tried hot glue and some scrub pads, but it doesn't stick for very long, and eggcrate has to big a holes.
Thanks ahead of time
