I brought my Betta home two weeks ago. I adore the little guy, he's very active and he loves his 5 gallon tank. I keep the tank heated between 75 and 80 degrees at all times. I feed him dried bloodworms 5 days a week and frozen brine shrimp once a week. I recently found out that the brine shrimp has mussels in it as well.
The last two days, he spends more time resting against his plants than usual. I'm not sure if the filter is a problem, it my be too powerful, though he hasn't seemed to have problems with it before. He still has a healthy appetite and he looks normal, but I'm worried that he's acting lethargic. Any ideas? I'm very concerned
