The lipid-rich TP diet may be suitable for commercial production of juvenile African cichlids up to 12 weeks of age, but prolonged feeding may result in excess lipid deposition and necrosis of the liver. Feeds like the FF diet, which produced slower growth but lower lipid deposition in livers, may be more suitable as a maintenance diet for cichlids in the home aquarium.
"Fatty infiltration of the liver has also been designated "the most common metabolic disturbance and most frequent cause of death in aquarium fish"
With prolonged feeding of a high-energy, lipid rich diet, degenerative changes of the liver and death can occur unless the diet is corrected.
