I have had this established tank for about 4 months now(recently added the Java mods and Amazon sword) and got this betta for half off at pet co. For the first couple weeks his colors brightened up and he was a bit bulkier than he is now. I’ve had him for around 2 months. But since I’ve had him all he does is lay around under the sponge filter and under the dragon stone. Water parameters are good and I feed small amounts of freeze dried blood worms. So what I guess I’m asking is, is he sick or just old?

UPDATE: Thank you everyone for your help! I’ve kept bettas for a while but have never had this issue which is odd. I am going to go to the store today to get some frozen brine shrimp!
