Yesterday I noticed that Sui wasn’t swimming around or eating much and seemed a bit depressed later in the day. My sister and I went out and got Sui a new tank with a filter, heater, and light. He seems much happier today. Constantly swimming around. We also just got some ghost shrimp to put in the tank since those are one of the types of animals that get along with Betta fish. Sui seems to be okay with them in the tank as long as they don’t land on him.
