Aquameta Aquarium Lid Insert Securely Fits Fluval Spec 5 - Aquarium Cover Allows Light Through Voronoi Mesh Design, Fish Tank Lid 3D-Printed PETG, Perfect for Aquarium Safety

I lost my betta when she jumped out of the tank (Fluval V). Before I got a new fish, I knew I needed to cover the hole in the lid. This product is a little expensive for what it is, but I am very happy with it and I feel like it will secure my fish. It fits perfectly, it matches the tank design and feel sturdy. I recommend it.

Works perfectly, the two pieces meet in the middle to cover the full open area. They sit on top, not snap in, but you could easily glue them in place if you wanted a secure fit. It still lets plenty of light pass through.

This fit exactly as should on aquarium. They do not “snap” on but lay on top in groves. A little high priced but looks great versus my own job. Recommend them

I needed to find either a different lid or another type of cover for the Fluval Spec 5 gallon fish tank, not because I was afraid my fish could jump out, but because our cats took an interest in drinking from and playing with the fish tank water. I was afraid this would make the cats sick, make the fish fearful or even hurt the fish, so I turned to Amazon to see what I could find. I thought about using the type of lid that was a mesh material, but could not find one the right size and I was afraid it would eventually rust. I also thought about adding something to cover the opening of the existing lid. I decided to revise my search to see if there was something made specifically to fit the cover I have and found this. Yes, it is pricey for what it is, but it looks so much better than anything I could have tried to add to the tank. You can tell it is 3D printed from close up, but it looks like it was made for the tank! It definitely serves its purpose

2 separate pieces fit perfectly in Fluval spec v cover

This is a perfect fit for the Fluval spec 5. I have a betta, and wouldn’t want him jumping out. Initially, I had some mesh over the hole, but I’m happy I found this. Easy feeds by just removing half of it.
