We have 7 Scissortail Rasboras in our 75 gallon tank. When they were in our 55 gallon they were very active, played tag with our flying foxes and roselines, just a fun school of fish to watch. Ever since we moved them they have been bumps on a log. Very boring, not active, not even when fed. The only thing that changed was the size of the tank and the lighting. Tank mates are all the same. 2 flying foxes, 5 rose line sharks, common sailfin pleco, red tail black shark, and a half moon beta. Water peramiters have been on point. Any ideas? Could it be the lighting?
