I'd ddefinately add some, if not all tilapia, and see if I could feed some GFC to help the CNBG. The Tilapia should help keep the algae under control and provide feed for the LMB, while the pellets will help the CNBG grow and prosper & they will feed the LMB while the Tilapia die off for the winter.
