How Baby-Proof An Aquarium

I couldn't find any good advice online on how to find a child safe aquarium coffe table. Most get involved by placing it on a higher and higher shelf (which is a big no-no in earthquake-prone areas, like here), and is one of the main reasons having a tank for my son to be able to keep the goldfish in To see inside.
I tried several temporary solutions that only lasted until my son could stand a little better or reach a little higher until I finally found one that works. It can be done for around $ 10. The first thing you will need is an aquarium that your child cannot move (mine weighs about 60kg with water in it). It won't help you prove your kid the tank if he can push your child off the table. The equipment required is--

-Aluminium (or coated wire of any kind)
- Padlocks (to lock small luggage - I got myself ¥ 100 in the store (the Japanese discount stores))
-A solid plastic tank lid (or solid plastic that can be used for the lid)
-A drill
-Wire cutter

The main idea is not to think of toddler-proofing an aquarium: it's about everyone-proofing it to think. Toddler-proofing really only works a few months until the child grows a little taller or a little smarter. If an adult can't open up, then you know you did a good job.

1. Get a lid

Glass lids won't work because they're too fragile for a toddler. Plastic lids are made for smaller tanks, but they were too small so I laced two together with aluminum wire. If you can't find a suitable lid, you can make your own. If the plastic isn't strong enough, you can sandwich a few sheets of the weaker plastic together to make them stronger.

2. Drill holes

You need to make holes for the aluminum wire. If the rim of your container is plastic, drill two holes on the lid, two on the rim for each lock. If the top of your container is metal or there isn't enough plastic drilling, you'll need to glue something to the side of the tank to hold the wire. A loop of some fabric (and flat) would hold better than a piece of metal or plastic in most cases. Epoxy or super glue should be able to hold it in place. When the filter is on top of the container, you can drill holes in the lid, too, to lock it in nicely.

3. Loop the wire

Aluminum wire has pointy ends when you cut, so make sure you put that on the inside. Twist the wire together a few times to see if it's strong enough.

4. fix it

Plastic coated padlocks are better (aesthetically and hygienically) for homes with young children. Since you have a lot of identical keys and locks that are identical, I recommend marking the key and lock with a permanent marker to say what's which. If for some reason the other steps don't work, somehow find your tank padlock. Different is just waiting for your child to get a little bigger or smarter.

To feed the fish without opening the lid, cut (or grind) a small divot on the edge of the lid to drop the food into. I don't feed the fish while my son is around in case he gets bad ideas. Now all I have to do is keep my son off the hammers and big rocks and the fish will be safe!
