PENN-PLAX Water-World Radius Desktop Nano Aquarium Kit – Includes LED Light, Internal Filter, and Mat – Perfect for Shrimp and Small Fish – 3.4 Gallon Tank

There were many mixed reviews about this aquarium so I was pretty hesitant to purchase it, considering I had to purchase two after my impulse purchase of male bettas.. I did a lot of searching to see what was out there and what would be best for my new additions, and this sounded like the best option since I don’t have enough space for two five gallon tanks. It’s a beautiful design, well packaged on Penn Plax’s part, (I purchased other stuff to go in the tank, it all came in one large box that was half opened on my front porch...) it had a cardboard box over the top and over the bottom, held together with two straps of whatever that plastic stuff is, and had the light and filter contained in another partial cardboard box inside of the tanks, and of course the tanks were in their own individual cardboard boxes inside of the large one. Along with the light and the filter, you are also provided a piece of foam in the bottom of your box to put under your tanks to protect the surfaces you put them on, so be sure to pull that out before tossing the cardboard! The filter didn’t come with instructions that were very helpful so I tried to go off of the other pictures people have posted on how to install it, and it seems fine. I’ll likely upgrade those as well as the lights that came with it, as they’re not the greatest lights and the only way to turn them off or on is to unplug them, which can be a little annoying. I read a review about the lid that comes with it, saying it was not form-fitting, but mine turned out to be perfectly sized. The downside to the lid is that it’s kind of easy to slide it forward out of its latches so my cat has tried to take advantage of that. The only thing I was not excited about was that the cardboard inside the tanks that held the filters and lights was hot glued to the bottom, so I struggled a little to get it out. Overall, it’s a great little tank for a great price, and my bettas love it, they spend hours swimming around the whole tank, exploring and whatnot. Would definitely suggest purchasing this tank! Keep in mind though, you’re having something relatively fragile shipped through the mail, so there’s always the possibility of it arriving broken, so don’t let that discourage you.

I love this aquarium. I purchased this for my dragon scale betta and hope to add some cory cats or shrimp...not sure which. I received the package and noted that it was in perfect condition. I opened the large outer box, which was marked with the Penn Plax name and logo to find a slightly smaller box with large bubble packs between it and the larger box. This box was unmarked. Inside the smaller box was the 10 gallon aquarium, safe and unbroken. Contents included the 10 gallon aquarium, rubber mat, plastic cover, correct left and right hinges for cover, light and Cascade 300 Internal filter. The aquarium is perfect...the silicone was applied evenly with no excess...the bottom was aligned with the main glass smoothly. The rubber mat is slightly larger than the tank so I set it so the excess was at the back. The lid so far servers its purpose...I only wish they added a plastic/tpu add on that could be modified/cut for cables etc so that there isn't about a 2 inch gap...Kind of what you would see on traditional tank glass lids. The light...I didn't bother with it. I find it inconvenient to have to unplug it every time...I ended up getting the Nicrew LED Aquarium light with Extendable brackets on a lightening deal. With the way the holders work on the brackets, i simply extend them and they attach to the sides and cover just fine. However, if I lift the lid the light slides to the back...so I just do it before.. The Cascade 300 Internal filter is ok. I like that it has two chambers that can be customized...for example, the bottom chamber has a sponge and the middle chamber has a cartridge with carbon...that chamber can be opened and the carbon replaced. Or you can do what I did...since the sponge chamber has a large opening in the center tube, allowing water to bypass the sponge, I purchased TAAM Rio Micro Pad and cut it to the shape of the filter...unfortunately, I will need to modify the outlet as the flow, even on the lowest, setting sends my betta drifting...I do wish they had made the whole filter black as the blue is a bit distracting and takes away from the rest of the tank, plants, fish, etc. I plan to aquascape in the Iwagumi style created by Takashi Amano...I have Eco-Complete black Substrate for plants and 7 Yamaya stones (they are inert and will not affect water chemistry). Will post more pics later. I would definitely recommend this tank.

The first one I that came in arrived completely shattered. Amazon was quick and friendly to deal with to send a replacement. The packaging from the manufacturer is subpar. There’s nothing between the glass and the cardboard it comes packaged in. Don’t let that deter you from ordering this great little tank. The glass is amazingly clear, and it looks stunning. The filter can be filled with whatever media you choose. The light it comes with isn’t great, but what stock lights are great anyways? If you plan on growing plants I would swap it out for something different. This is a great little tank for a school of nano fish, a few pea puffers, a beta, or a colony of shrimp. I would recommend it to anyone looking for a 10g or under aquarium.

The aquarium itself is great, sturdy glass, the rounded corners give it a much smoother look. The size is perfect for a Betta or perhaps an aquatic frog. The filter however is the biggest and loudest filter I have ever seen, I'm shocked other people said it was quiet!!!! It's not! At all! Makes the whole aquarium vibrate and the current is way too strong even on the lowest setting for such a small tank, especially if you are getting a Betta or aquatic frogs who are not strong swimmers and are easily stressed by noise and vibrations. The lid is very flimsy, it works okay but the 3in gap is a bit large and fish could easily jump out. Basically, be prepared to buy a seperate filter unless youre keeping active fish who don't mind noise and vibration... You get what you pay for I guess!

This review is in the perspective of an aquascaper and aquarium enthusiast. Great tank, the glass is thick and the curved corners make for an awesome view and a great addition to a Nano aquascape. Not sure why people were complaining about the lid, Ya it's flimsy but why would you want something thicker? Its more then enough and gets the job done and it's looks neater being thin and light weight, it also has a large gap near the back, because it's for easy filter maintenance, you don't have to remove or open the lid to get at the filter. The lid hinges are a great design, I love how you can open it to feed the fish, or you can easily slide the clear plastic out of the hinges, to clean or perform maintenance on the tank. The included light is definitely subpar. It's better then nothing for sure but I get why people were complaining. 1. It's not really bright (this only really applies to growing live plants) and 2. No on and off switch (yes you can use a timer). Other then that I mean it's ok as a spare light, or maybe you can find another purpose for it. The internal filter is so far so good. The flow is kinda high for a Betta even when it's set to low (yes it has a flow switch) but if you angle the outflow head to the side of the tank it blocks most of the flow from disturbing the Betta. On high it's actually quite a powerful flow, good for cycling the tank before you add a fish, or shrimp etc.. The way it has a built in air bubbler is really neat, I don't use it because I have a Betta , but I did try it out, and it works awesome , however the filter can only be about 1/4 inch under the surface of the water or it won't blow bubbles (guessing you might be able to fix that with a longer airline tube) Really the only draw back to the filter is the lack of filtration it can provide and how fast it clogs. Itsreally small which is good for aquascapes, though the size of the media basket cant hold really anything that big. I got away with using bioRings smashed in half placed under the stock sponge. Its definitely better this way over stock, but still not really that good. Wish the filter was slightly bigger in length for more media to fit. I took a star off because the way they include all the extras (light, filter,lid) in the tank, they siliconed a box with all of the above mentioned to the bottom of the tank glass and was really hard to remove , also felt like I was gonna break the tank trying to get the box out as well as remove the silicon from the glass (see photo) Overall super pleased with this tank! I will update review after a few more weeks. But so far really decent value for a nano aquascaping tank that would normally be alot more in cost from a dedicated aquascaping store. Update , Sept 26 ,2019. Tank is still excellent , no issues with anything since I've bought it. I've changed the light a couple times till I was happy with one I found (nicrew flexible clip led) and I changed the filter to a azoo mini hob filter that is way way better then the stock one this kit comes with. Overall still amazed at the quality of this little tank! If you liked this review or found it helpful , I would really appreciate it if you give it a like! Thanks

Ok. So where to begin. The light is crap and needs to be upgraded. The filter is surprisingly quite strong and is adjustable. The only downside is it's only a small sponge and I like to use some bio media. So I purchased the cascade 20 that comes with the 2 gal version of this tank.. which works like a charm. The first tank I received had a few scratches in it and the silicone was shady at best. The bottom was actually missing some and the glass was down a tiny bit and very sharp. I could fit my fingernail between the two pains of glass.. for an item suppose to hold water. That's not good lol..So I returned it for another, which Amazon was amazing and told me how to do it. (My first ever return). And the second was perfect! Will make a great shrimp tank. It wasn't Amazon's fault for the shoddy work of the first tank. But they replaced it with no issues. And for that and the second tank 5 stars! 😊

Nothing else to say but that it’s cracked finished no good. Very disappointed
