Koller Products5-Gallon Aquarium Kit with LED Lighting and Power Filter, Ideal for a Variety of Tropical Fish

I love this aquarium. It is the perfect size for my small desk and perfect for college students who want a little pet fish to keep them company. It only takes up a little space, but it is very spacious for the fish to swim around. I also really enjoy that the filter that is included only takes up a little space in the tank. The light that comes attached to the lid has so many different colors and light settings. The aquarium was very easy to set up and do water changes. This fish tank was effortless to set up in as little as a couple of minutes. This tank is excellent for its price as well as for its size, and it is a great value for your money. My betta fish, Bubbles, really enjoys his new home and is thriving with all the swimming room he has. You do have to be careful when cleaning the walls as it is acrylic and can scratch easily. The shipping was relatively fast, and the aquarium came in perfect condition. At first, I was a bit skeptical with some reviews saying that the light didn't work and the filter stopped working as well after a couple of months, but I was pleased that my light and filter are still working perfectly after four months, and it is going on strong. Although the filter didn't work right away, it did take a couple of minutes to see the water flow out of the filter. Overall, it is a really great purchase, and if I get another fish, I will buy another as the aquarium quality is excellent for how much I am paying. This product is a 10/10, and I recommend it to others looking for an aquarium around this price range.

The media could not be loaded. It is great aquarium, we have it more then 3 years and still looks great, easy to clean , perfect size for small fishes. It was easy to set up and we had different colors of lights that makes it very cute and we enjoyed how our fishes were there.

I like this tank just fine as a beginner (and for my 3 year old's room). I haven't had any major problems with it in the past 8 months since I bought it. The fish seem happy and healthy, we have added and traded fish with no problems. It took some time at first to keep the water clear and fresh smelling, but fixed itself.I change the filter about once a month or so and rinse it about once a week. The filter usually starts sputtering when it needs to be replaced. (the tetra whisper filters fit and are cheap.) I change out about 1/4 of the water once a month as well with a gravel vacuum syphon thingy. (I unplug the filter when i change the water- I think I almost broke it the first time by leaving it on.) The filter is very loud when the water flow is not covered with a high water level, but most reviewers say not to do that? I always keep the water level high so it is quiet and have not had any problems.My daughter likes feeding her fish and changing the light colors. It does seems to scratch easily and now has some green algae specks that don't come off when I occasionally wipe down the inside- not sure if a glass tank would be better with those issues? Overall happy with this basic tank- just make sure to get some replacement filter cartridges.

We got this for our betta fish. It's our first fish. After about a month, the filter was making a strange noise and then stopped working. I reached out to the Koller customer service. They were awesome. They very quickly sent us out a new filter. We left the original filter unplugged for about a day and then tried plugging it in again while we were waiting on the new one to arrive and it started working again.If yours is acting weird, make sure the water level is high enough.We got this heater with it: https://www.amazon.com/gp/product/B07S1WXJ3F/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&psc=1It perfectly keeps the tank at 81 degrees.We initially got this heater and it made the water too hot: NICREW Submersible Aquarium Heater, Shatterproof Adjustable Betta Fish Tank & Turtle Tank Heater, 25-wattBe careful not to overfeed your fish! We definitely were overfeeding ours initially and it stopped eating. We had to fast it for several days and then started feeding it daphnia along with its other food.The best advice I saw was to feed it food the size of its eye, twice a day. We fast it one day a week now too. And feed it daphnia all the other days in addition to regular betta food.

Okay by far I very much like this tank, it’s so sturdy and honestly so amazing, it’s very good price and perfect size for my betta, the filter works amazing as well the light. My betta fish loves it and I love that he loves it, at first I will say I was worried the filter might have been a little too strong my my little betta but he got used to it and swims great. I’m a first time betta fish owner, I did a lot of reading and lots and lots of research, I’ve spent over 100 on this fish cause I love him, and only plan on spending more. I wanna give him the best life possible, and delete all the trauma he has had from his little cup. He looks beautiful. Anywho the tank came with clear instructions, and good solid filter. I bought the heater on my own, which I would recommend and cycled his tank with quick start and conditioner as well as added an almond leaf for good medicine. I hope he loves long. So to conclude GET THIS TANK 🫶🏽🫶🏽

We like the optical illusion that the sides of the tank gives off but the light mysteriously turns on after we turn it off every night. Wish there was a better button option for this light.Also, the way that the light settings are function toggling through each different light option is not working well.Being that the walls of the tank are not glass but a plastic material, fish fences stain the walls.Will be reaching out to the company to see if they can give us a new top to the tank so the light doesn’t turn on after being turned off.I will update if they help me out.
