What fish work best with this tank?
Answer by ChewyJan 16, 2019
This aquarium is appropriate for keeping up to three small community tropical fish, such as guppies, cardinal tetras, or goldfish.

Since this has a filter do you have to change the water?
Answer by ChewyFeb 14, 2018
This aquarium is recommended to be cleaned on a monthly basis to better clean the gravel. However, we recommend to use a turkey baster once per week to stir up the gravel and remove some debris while taking out the water and then adding new water. When the thorough cleaning is done you still only re place approximately 25% of the water.

Can you still use the led lights without turning on the bubbler? Does the lid attach/ snap in place or just sit on?
Answer by ChewyMar 05, 2018
The lights and bubbler are attached to the same plug, you can shut off the lights and just use the bubbler but not vice versa. The lid rests on top of the tank, it doesn't lock in place.

Is this made of plastic?
Answer by ChewyFeb 12, 2018
The tank is made of acrylic.

Cute and inexpensive

Overall, this is a decent tank for the price. It has a couple of cons that are really more inconvenient than anything. First, it is frustrating to get the bubble stone to stay in the bottom of the tank. When I would finally get it to stay, I pulled the wire just slightly trying to move something else and pulled it out again. Next, the lid doesn’t fit just right. It’s hard to get on, which has actually kind of worked in my advantage because the cat cannot easily get it off. The last thing is that there end up being a lot of wires and cords in the tank, between the airstone tubing and the light cord and the tubing to the filter, then a heater on top of all of that. I do enjoy these tanks and the lights and bubbles!

So this Fishtank was super cute and when I bought it it was on sale so really cheap! Compared to most other fishtanks it’s relatively compact and comes with everything that you need to get it started, BUT the worst part of this fish tank is that the back of it is a flat surface SO because of that, once filled up like it supposed to be it bows a little bit which makes me super nervous!! When you put the lid on you kind of have to give it just a tiniest amount of push for it to be on correctly. I think they need to take that into consideration and kind of give the back a little bit more of a curve. Other then that. Super cute and affordable.

Filter isn’t working

I’ve been happy with the tank so far, but now the filter stopped working. I’d like to replace it with the same one because I have a stockpile of filters but I can’t seem to find the exact one. Can you help me find the same model to replace?

Decent I suppose

It’s a decent tank for plastic. I like the idea of the filter running off the air pump. However, I just received mine today, got it all set up and the ‘bubble curtain’ barley bubbles at all. I’ve tried taking it out and washing it, unhooking it all and rehooking it up, unplugging multiple times and turning the valve off and all the way to max. It barely has a single trail of bubbles. This is pretty disappointing considering the bubble curtain was the whole reason I bought this tank. Also, after it was filled with water, the lid has to be forced on. I checked it beforehand and it fit fine.

It’s good.

Its good. my betta fish likes it, but you do have to clean it alot. not THAT often but around every 2 weeks or so. But besides that, there was nothing wrong with the tank or anything, I would recommend.

I purchased this tank for my beta. I loved the idea of the LED bubble curtain. I was very disappointed. No matter what I did it didn't work correctly and the filter stopped working after only 2 weeks.
