Diversa Aquarium Professional Fish Tank - Real Glass, Standard Rectangle AQUARIUM ONLY - 12L (30x20x20cm)

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.

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.

Perfect size for a posh bedroom lamp. Arrived in a timely manner, and well packaged. I would certainly buy another from this company

Amazing tank, i dont really like the glass pane in the middle as it meant i have to get two leds instead of one long one. But love my tank :) fast no hassle delivery. I have had this tank a year now, ive knocked off a star (maybe even two stars). The reason for this which i did not really look into when i first got into the hobby is for the following: firstly the black silicon is not the best looking, a clear one would have made the tank look like some of the more expensive brands, also the tank i recieved the glasses were not even touching and some corners are only connected by the silicon and i can put my fingernails between two connecting glass corners (pictures to follow), another erk i have which dident really bother me when I was an unsuspecting novice is the brace is not right at the top meaning you cant really fill the tank up the full 300L. When i first brought the tank i was very pleased but now having researched a lot more for my next tank i feel there are better products out there albeit a little more money. In conclusion for the price (and the size) its a decent product, if i could rewind time however i would be willing to spend a lot more on a more athletically pleasing tank, i feel i will upgrade in the next year or so because of this. Ive kept it at 4stars because its a nice clear tank and if your short on cash its a good product but not something that can be matched to something like a evolution aqua.

So far so good. It came with very simple and clear instructions for testing the tank is watertight, preparation, situating, and cleaning. Comes with a mat to place it on, explains how to position it all and why. No leaks after having it full all day so now seasoning with plants and straw bugs before adding fish and snails later. It will serve as a great fry tank for my shubunkin pond. Looks great with neat black silicone edges, glass was perfect and clear with no blemishes. Packaged very safely with mainly cardboard and minimal horrible polystyrene, just securing the corners as necessary. Prompt delivery. *update with updated photo: It's still holding up well, no leaks or discolouration, perfect.

40x25x25 tank arrived on time, and intact, well packaged. The edge seals are nice and neat, and it holds water with zero leaks, so far at least! I’ve only had it 48 hours, but so far so good. An excellent little tank, especially at this price.

I bought this tank for sump for my marine aquarium intought it become perfect.. Diversa tank is leaking/glass cracking at the bottom front left corner. At first I thought the puddles were just water splashes...a bit of a show-off...and I could not spot a crack. However over the last couple of minutes the glass is definitely showing signs of leaks are more obvious. I have had several tanks over the years have never encountered this issue with other brands. I will definitely not buy another Diversa tank.

Ordered 10x 54L tanks. Seem like high quality tanks. Some issues during transport but sorted out quickly, not the fault of the seller. Very happy with service, would use again, thanks.
