    • Great for Inverts! (Too small for fish)

Honestly pretty impressed with this little tank. It’s only 3.5 gallons, so not actually big enough for any fish (especially as the swimming space is even smaller than the), but it IS a great invert tank! I needed something to culture black worms in for my community tank, and I didn’t want to just use a bucket, so I decided to use this. I added some Malaysian trumpet snails and bladder snails, and will be adding some neocardinia shrimp in a few weeks. The light is adjustable so it’s quite versatile, although I’m unsure how well the spectrum will grow plants yet. I really just have easy, low light plants in the tank though, and added catappa leaves to give it a blackwater/swamp look, so it should be ok I think. The filtration is slow but the amount of bio media in the back is way overkill for this size of tank, so I’m pretty happy about it! It’s not much to look at yet since I started with a small starter culture of works and three bladder snails, but I’m very pleased with the aesthetic! The pump was noisy for the first hour, but once it had been running a bit it quieted down nicely! The lid isn’t amazing, but it works and keeps my cats out, and I got this because it was reasonably priced for what I wanted, so it was worth it imo :) ... show more

    • Easy Setup, Cheap Thermometer

Tank setup was fairly easy. Light settings all work very well. The only issue was the thermometer. It filled with water, came loose internally, and can no longer be properly read.

    • reminder that returns are not accepted for this tank
Size: 3 Gallon
Review Image by Cody Cummings Cody Cummings
a little on the pricier side when comparing to the kits you get at petsmart or petco. especially when they have sales. they also accept returns should the tank not work out for you. i do not like how there is a drainage hole at the bottom. also the betta can see his reflection so he is constantly flaring. a shame that returns are not accepted for this product as it did not fully meet my expectations. you are better off with a rectangle glass tank to avoid the reflection and the added stress on the fish. light in photo is not the light that came with this tank. wish the tank was a little larger but that’s not the fault of the company. the filter is also a little too strong for our fish. overall all pretty happy. this is my daughters first tank so i am sure she will want to upgrade at some point anyways. ... show more

    • Decent tank for the price but not perfect
Size: 3 Gallon
I’ve had many fish tanks in my life, used to have a 55 gal. Sold all of it several years ago so we decided to get a small tank for beta fish. This tank is a great starter tank as it comes with everything you need at a reasonable price. However, the lid rim does not sit securely on the top of the tank. For our use it’s not a big deal as the light can still sit on top. ... show more

    • Moldy broken filter
Size: 3 Gallon
It would be great, but the filter has never worked properly. In fact the filter spout (where the water is supposed to pour back into the tank) has water sitting in it barely dripping out, and now mold has grown on that area… would love to get a replacement or refund or helpp. Bummed and annoyed
