Pawfly 4 Pcs Aquarium Grid Divider, Plastic Fish Tank Divider, Egg Crate Divider Tray, Grid Fish Tank Bottom Isolation Separator for Aquarium Fish and Plants, Black

Strong and sturdy. To assemble, place panels on hard flat surface and use a rubber mallet to gently tap tabs into place.

These are very hard to fir together and were took large for the tank I was using it for.

Pawfly 4 Pcs Aquarium Grid Divider, Plastic Fish Tank Divider, Egg Crate Divider Tray, Grid Fish Tank Bottom Isolation Separator for Aquarium Fish and Plants, Black I had a different than intended use for these grid panels. I am using them in my rabbit's litter box. Rabbits tend to #1 & #2 while eating hay, so it is common to just put some hay in the litter box. But normally, the hay would be in contact with the litter, #1, & #2. So what I did was first put some compressed pine pellets in the bottom of the litter box. You can get them at most stores that are "rural" or "tractor" themed. I then put the grid on top of the pellets with the side with the flatter edges facing up. Hay is them placed on top of the grid so bunny can sit on it or eat it. Now, I can easily lift up all of the hay to clean out the bottom. It seems like the grids may be 3D printed. I'm not exactly sure. However, there is a lot of excess plastic on the edges, as you would get with a 3D print sitting on the hot bed. I had to trim all of this off before I could get the panels to snap together. This ideally should be done in the factory before shipping to the customer. I gave the grids 4 stars since they should be ready to use when received, but aren't. If used in an aquarium, you will need to devise some way to keep the grids from moving around or floating upwards. They don't include anything to do this, nor do they offer any suggestions at all. I think they should include a "T" shaped end piece. This way you could put some decorative rocks or weights on top to hold the grid in position.

Pawfly 4-pack aquarium grid dividers are highly malleable, and the baffle in the middle is very good. The baffle is made to prevent fish from fighting. The most satisfying point is that the size is regular, so it is very convenient to splice. Even if you cut it horizontally and splice it vertically, the interface is completely aligned, and it is very strong after splicing.

The tabs are too wide to fit into the intended slots. Couldn't get a single section to connect to another, no matter which side I tried. Ended up using zip ties to hold them together.

This divider works well in our tank! It stays together nicely and is pretty thick material, so I'm not worried about it breaking. Very reasonable price for what it is and works to keep my fish isolated.

Came exactly as described. They feel durable but are a little hard to get to lock in.

I used the "Pawfly 4 Pcs Aquarium Grid Divider, Plastic Fish Tank Divider" as an aquarium cover to keep my flying Beta fish from un-aliving himself trying to see the world. The plastic is thick and the grid is the right size. The panels take considerable force to snap together, which is good because they stay together. Place the panels on a flat counter top, and press one connector at a time together with the heal of your palm. I did not use as a divider, but you would need suction cups (not included) to keep it vertical inside the tank for that purpose. After measuring (see pictures), I cut the overhang with tin snips. You could use heavy shears or a Dremel tool. Regular scissors won't work. I recommend as a top cover for small tanks, but not as a divider since a way to keep it in position is not included.
