Has anyone ever had a tank where the fish were not active? My tank is boring! The fish don't swim much, they don't interact at all. The only time they come out of their spaces is to feed. Then they eat and then go back to just sitting around. This isn't new. It's kind of always been like this . Nothing has changed. I have tried keeping the lights on, turning them off, changing temp, checked the water levels, I rearranged the tank to see If that would liven them up and nothing! . Any suggestions???
