I've had this aquarium for about a year now and haven't had one problem with it! I have it set up as a betta tank with real plants. The light is good enough for low-light plants, grows them perfectly! Will be buying another one soon for another betta! Love it!

Bettet than I expected

I bought the 5g with some skepticism a few days as a hospital tank which will eventually become a pemanent home for one of my males. I got it home, took it out of the box & actually liked the way it looked much better in person. I have it set up bare bottom, with some silk plants, a decoration & a sponge filter. I didn't use the in-tank filter as I don't like them & I didn't set up the light because I don't currently need a light. I would prefer if the lid had a door rather than a cut out for feeding but I do like that the back part of the lid is already cut for filter & such, hopefully that is the set up you'll want. Bottom line . . . love it!

I love this aquarium. It is perfect for my office desk.
It is very easy to clean and maintain. I would (and have) recommend this tank to anyone who is setting up a non-planted Betta tank.

This tank was easy to assemble, the filter is included, light is included, just wish it had a small 25 watt heater. I use this tank for by betta fish and he is real happy. No rocks or plants or any interior stuff is included, so be sure and purchase them too! Tank looks great and stays clean. Only thing is at 4 gallons of water I was so close to the top, don't think five would even fit, but if it did, one little wave from the filter would put the water over the edge! So really it is a 4 gallon with about a 1/2 inch space to top of tank. Also tank has no rim on top so water easily goes over.

I have the smaller size of this aquarium as well as the 5 gallon size. I enjoy both of them and my bettas have been very happy with them as well. The filter setting can be changed to the lowest speed and it does not interfere with my betta's swimming or create fin problems. The light is nice and bright and the filter is quiet. The only issues I have encountered are ease of cleaning and the open spaces on the lid. Because the tank is acrylic you must be careful when cleaning so as not to scratch it. I would prefer that the lid have a hinged door in order to feed so that I would not have to cover it to make sure my betta doesn't jump. Otherwise, great looking and functional tank!

I bought this 5 gallon tank for my Betta, but the one I bought didn't have a lid? The tank keeps getting dirty (even though I clean it regularly)- but that is probably is because mine was missing the lid (which is really annoying to find out). Another thing that is a pain is that I am constantly having to add more water because it exaporates so fast. I have two Betta tanks (different styles/brands), and this one evaporates so much faster than the other.

This tank is easily assembled and managed. The filter is great, I have unclear well water and it cleared it up in just 24 hours. The LED light is awesome, lights the tank perfectly and doesn't produce hardly any heat. It's so affordable considering how awesome it is, I love the shape and way it's designed, bow front aquariums are so pretty to me. It has a nice clear lid, with a small slot for a thermometer and fits around the filter and LED light with neat grooves in it. Overall, I'm so GLAD I chose this aquarium above all the others available. Fits right on my desk!

I really like this tank, but the feeding and filter holes are too big. I don't know if I'm the only person with this problem, but it's highly inconvenient to have to pick my fish up off the floor and drop them back into the tank, hoping that I got to them before it was too late. Otherwise, the light is very bright and not too hot, and the filter is absolutely silent and very efficient.

This tank was a gift to me. Although it has a nice design and is a good size, I wish it were a bigger tank. With the filter, (which is mediocre on performance and does not airate the water) air pump, and heater, it gets crowded. It came with a plant and I bought a small rock arch aswell. i have two little girl platys in there right now, starburst and lemondrop, and it is an okay tank but I dont think it is worth the money. I would just get a normal 10 gallon instead. It takes up the same amount of space and you can do more with it and it is probably cheaper.

I got this tank for my first fish. (Betta Fish) At first I didn't want to get because I didn't want to deal with the filter but I got it anyway and I love it. the filter was easy to put together and only has a slight vibration. I love the adjustable flow! I had it all the way up and it was a bit too fast for my fish so I took it down two notches and it's great.The filter cartridge is also very cheap and is not eating at my wallet. The LED hood was also very easy to put together and it might be a bit too bright so I turn it off when I'm not looking at my fish and snails. The shape of the tank is perfect for the corner of my desk. Overall I love it and recommend it.

Good idea that does not work. The light is great. However the filter overflows a lot of water outside of the tank.
I would like to return mine, but difficult to do that without harming the fish.
Very expensive for something that does not work properly.

I purchased this tank for the first time about 6 weeks ago. Within a week we noticed the tank was cracking everywhere, so to be on the safe side we took it back so it did not leak. Then we exchanged it thinking it could not possibly be every tank. Within 3 weeks I had fish tank water all over my brand new bookshelf, carpet, and all my daughters toys. They leak so easy. The rest of the tank is perfect we loved it, but a big part to a tank is that it NOT leak!!

Pros: easy to install, easy to clean

Cons: flimsy

I got this fish for my betta. He was in a one gallon tank before and he was so happpy when I finally upgrated and put him in this tank! This tank is so beautiful. I gave it a 4 because the filter makes a lot of noise. I'm going to clean the motor out but, if that does not fix it I am going back to Petsmart to replace the filter. I love this tank and so does my betta! However, do NOT attempt to put Goldfish in this tank because they are way to big. Only Betta, guppies, and maybe a small tropical fish should inhabit this tank. Overall, it is beautiful and wonderful for my precious betta!

Pros: easy to install, easy to clean

Cons: hard to clean, flimsy

I really like the tank. I bought it since it was ten dollars off and my betta needed to move up from the three gallon it was in. It is very nice and bright, the only thing I don't like is when the water evaporates and beads on the plastic cover. Still looks great though.

Like watching a high def, 19 in, screen saver. The clear plastic top gives it an infinity pool effect. Has sufficient cut outs for heater and other items (see pic). Like half moon cut out in front to feed. Great lighting during the day even in a bright room. LED looks like a Hollywood marquis at night. Very quiet filter. I prefer larger kits but had one corner in my office that needed something. Best small aquarium set up I've had.

I'm going to add a few smaller plants and maybe a background. I just set it up last night. Super easy! Today I'm going to get a couple guppies and maybe something for the bottom like shrimp or a crab. It's perfect for my toddler's room.

Pros: easy to install, sturdy

The first thing I must say is, GET RID OF THE FILTER. It is way to big and way to powerful for this tank. I turned it on low and it was still to powerful. I love the LED lights. They are very bright and make the tank look so much better. They are also helpful when you do water changes.The tank is easy to set up. If you have a heater, be prepared. You will have to add water frequently. The water evaporates very quickly because it has large openings in the lid. The curved front make the fish look bigger at just the right angle. I also like how they have the tank elevated on a little "stand". This is a very nice 5 gallon tank minus the filter.

i bought this tank for my betta Thor. i love it and so does he. it's a great size for a betta, i have his hammock, floating log to hide in, some rocks, a few plants, the heater i bought and the filter that comes with it and it is plenty big. it is extremely quiet, quietest filter i've ever had. super easy to see Thor, feed him, clean . It's perfect and the price was great in my opinion. Petsmart also has lots more great fish stuff than most other stores . I just cut the background paper to fit around the tank, no prob. I happen to love the led lights and have no problem seeing in the back . just a great tank.
