$20 · 2.5 gallon Betta fish tank

I don’t suggest using the divider because it is too small for the betta to live in with the divider, but without the divider it is plenty of room for a betta, it’s half the size of my 10 gallon currently which is lots. I painted the back so the betta couldn’t see his reflection but it’s not noticeable from the front. Bought this for like 35$ and everything is there and works well. The only thing you’ll need to get is filter cartridges and it’s 5$ for two and they last a while. I only used it for a couple months but it’s an amazing beautiful tank. I cleaned the decorations and gravel once every three weeks and changed the filter cartridge every 4 weeks, don’t clean at the same time that will shock the environment. It is easy to carry to a sink and even dump out and fits in a medium sink. Comes with an led light too and filter, lid, everything.
