Hi, I recently had a fish from my fowlr tank go carpet diving despite the fact that there is a glass top. There is a small gap at the back for the hob filter and he apparently went rocketing through there. I would like to put a mesh top on with little to no gap but it is a hex tank and all the diy kits seem to have 90 degree corner pieces. The screen may not stretch out right, anyway. So, any ideas for other types of tops? The tank is a hundred years old and the original lid with the plastic piece at the back is long gone. Can't recall the manufacturer at the moment. Starts with an A but not Aqueon.
Thanks.
Thanks.
