Review: Wonderful tank that you can customise yourself! - I’ve waited a few weeks before writing a review just to be sure that nothing surprising happens. Thankfully after 3 weeks so far I’ve had no issues with leaks, the tank is really well sealed and the silicone is very neatly done also. The glass thickness is a on thinner side ruffly 3mm but for a 25 litre fish tank that’s reasonable(other reviews have stated that the thickness does increase with the amount of litres it holds). The glass is also appears to be flo-glass (greenish tint) so if you’re looking for a white clear glass look this might not be the one for you but overall for the price it’s definitely worth it for a first rimless tank.
Review: Very Well Packaged - I couldn’t be happier with the Diversa Aquarium Professional Fish Tank. From the moment it arrived, I was impressed – it was extremely well packaged, with plenty of protection to ensure the glass was safe and intact. The tank itself is absolutely perfect for my goldfish. The dimensions are just right, giving them plenty of swimming space without taking up too much room in my home. The glass is crystal clear, which makes watching them a real pleasure – it feels like having a little slice of nature indoors. Overall, the build quality, clarity, and practicality of this aquarium are spot on. I would highly recommend it to anyone looking for a professional, reliable tank for their fish.
