in a 292 liter tank ? This is quite overcrowded !!!
Fronts should not be kept in tanks less than 2 meters long and about 800 liters.
Trets can be very agressive fishes, specially intraspecific behaviour.
Sexfasciatus are rather big lampros and, IMO, a larger tank is better.
In your tank, you can try to keep ONE of these 2 species, I'll never try 2 (even if I never kept trets ans sexfasciatus in the same tank)
