Lol, yeah, that's cute and all, but there is no way that flimsy little table is going to withstand the weight of your aquarium! Not a chance!!
Backfromthedead
is obviously trying to pull a fast one on you; he likely saw all those
convicts bopping and smacking and juking in all your tanks, and hopes that you will have a tank disaster, throw up your hands in defeat, and give him all those
convicts which he will then use as feeders.
You need to fully enclose the sides of that little coffee table he built you with premium hardwood 1-inch plywood, then drill a hole into the centre of the top and carefully pour it full of structural-grade concrete. You'll also need titanium-reinforced support rods under the floor, resting on screw pilings that have been sunk at least ten feet into the ground beneath, or until you hit bedrock, whichever comes first.
DO NOT do anything simple. Never react...when you can overreact!!!
Too much....is just barely enough.
