Everybody buys and keeps Betta fish in small jars and small bowls with no heater or filter, which kills the fish in the end. They are only sold that way so they could be put next to each other to compete and show their fins and raise the possibility of being bought. Selling marketing is showing the wrong picture bout caring for these guys and they often die very quickly of sickness and in pain.

They need much more and deserve better.
