My Betta is in a 5 gallon fluval chi tank. I had two ghost shrimp which were in the tank when they were little and I introduced Bubba into the tank shortly after. They all seemed to get along fine. The shrimp would occasionally chase Bubba and he would ignore them, occasionally chasing them away. They got pretty big, about 2 inches. I would usually feed Bubba at the top and sink a couple betta pellets to the shrimp. I had a big ball of betta pellets clumped together and I sunk it for the shrimp. They carried it around and the next morning they were both dead. Not sure if they overate or not, but Bubba seemed a little sad that his mates passed. He's been in there alone now for about 3 weeks. He seems to survey the tank a lot more now instead of hanging at the top. Not sure if he's looking for his mates or if he's enjoying the solitary life now. Just asking if anyone thinks I should get new shrimp, or let him enjoy the tank to himself. He was never really violent with the shrimp, they all seemed to get along fine other than chasing each other occasionally.
