So I was wondering if there is a product or if there are any precautions to be made to keep fish out of the overflow? I use a 1/4 inch netting top on my aquarium and this thing is not exactly heavy. Anyway I have a big strong wrasse that likes to jump out of the water several times a day and slam into it. Last night the wrasse jumped, moved the net enough and got stuck on the overflow, splashed around like crazy and ended up in the overflow... I got him out but this is roughly the 8th time in a month. Does nobody else go through this? I have never seen a thread about this but what are some of you doing to prevent this or does everyone just deal with trying to catch the fish out of the overflow? Mine is not easy to reach and I really don't ever want to do that again...
