Fluval Chi 2 -- Pros & Cons

 
1. As I mentioned already, the Fluval Chi aquarium kit is absolutely stunning and on top of that, it doesn’t take up too much room so it can go pretty much anywhere (bedroom, kitchen, bathroom, living room, etc.). It also comes with almost everything you need to get started with betta fish: aquarium, filter, LED lighting, water conditioner, etc. The bubbling sound that the tank makes when the water spills over is also extremely relaxing, which makes the tank even more pleasant to look at. At least in my opinion.
 
 
2. I like the way they designed the filtration cube because you don’t have to take it out to change the filter. All you have to do is rotate the cube and open the door underneath to remove and replace the filter. It definitely makes cleaning the aquarium that much easier.

3. The LED lighting is also very powerful compared to other aquariums around the same size, which is great if you are planning on growing live plants in your tank.
 
Ok, now for the downsides. Earlier I said that the tank comes with almost everything you need, except for a heater. If you are new to the betta world, then one thing you need to know is that it is extremely important to have a betta fish heater if you want your betta to survive the long haul. So important that I wrote a complete blog post on it -- see Importance of Having a Betta Fish Heater. If/when you buy this tank, just make sure you buy a heater to go with it.
 
Another thing is that the water seems to evaporate a little bit more with this aquarium. I don’t think that’s just the case with my set up because other people have been commenting about the same in different forums. Not a big deal, just make sure you keep an eye on it and fill it up when it gets too low.
 
Overall Opinion -- This Fluval Chi is a fantastic selection and one of my favorites for holding bettas. Not only is it efficient and very easy to care for, it’s also has a very elegant design and looks great just about anywhere.

  1. This is the BEST….. TANK….. EVER! 🙂 As you can tell, I love this one. I started off with tetras in it, but I eventually made the switch to Bettas and haven’t looked back. 🙂

    1. Hi Julie, thanks for the feedback. Definitely agree with you, it is an amazing tank. And yes, once you have a Betta, there is no going back! 🙂

  2. Any ideas on how to house two male bettas in this tank? If it’s not possible, it’s not the end of the world but I’m trying to house four males without my house looking like it’s a pet store.

    1. Hi Amy – Males definitely don’t like to be put together, so the only thing you can probably do is try a divider. But if you have 4 males, you would need to divide your existing aquarium into 4 compartments. Definitely don’t try to put more than one in each compartment. Unfortunately, that’s just the way it is with male bettas. I hope this helps. Good luck! 🙂

  3. Hi – I’ve had this tank for several years and had no success in keeping a variety of fish alive. I was advised to get 1 black fish and two colored fish by a Feng shui practitioner. The nitrates despite my cleaning and not overfeeding was an in and off again problem. Then my fish would just die ?? I read your post and wondered if you think a heater is necessary even when room temperature with heat in Winter is high and water temperature says 82 degrees. Also I’m wondering if you think 3 betta would work with one black and two colored

    1. Hi Sara. Sorry to hear about your fish problems. For your first question, I always recommend a heater, even if the room temperature is high enough. Mainly because you can’t predict a sudden shift in temperature (even if it’s a few hours) and bettas don’t react that well to drops in temperature. The heater would be a good backup. As for the number of bettas, I would stick to only one. Bettas are extremely territorial. 5 gallons is not enough for 3 bettas. However, if you are going to try 3 anyways, make sure you get them all young and they have to be all female. If you add one male to the mix, it’s not going to end well. I hope this helps.
