I got this for my beta last year. It has worked great and really shows my beta nicely. The filter works great as does the pump. It is just the right size for a desk too. The style makes it look like it costs a lot when it was really very affordable for all that you get.
This was an amazing tank,I still own it for our 2 turtles and they love it.the lights are gorgeous and makes the tank look neat when you get glow in the dark rocks like we have.super easy to clean as well.very worth the money.
It really just depends on you. Some people believe that smaller tanks are harder to stabilize, whereas some think it's the larger ones. At this size, you would need to do frequent water changes or have plenty of live plants to keep he water clean.
