Lee's Betta Keeper Hex Aquarium Kit

People saying this is too small for a betta fish. No it is not. They need small spaces without moving water as that is what they live in naturally. Filters are not good for them as it moves the water around and pushes them down making it harder for them to come up for breathe of oxygen, yes they breatheoxygen from the air. I had this exact tank and had a betta live in it for 2 years. Requires frequent water changes. Only use distilled water and dont leave the lid on all of the time as they come to the surface to breathe oxygen. Please research the pet you intend to get beforehand.

I can't imagine keeping a Betta or pair of guppies in this little bowl for any length of time. I use it to hold a Betta while I change the water of their larger bowl.
