Never starve IMO
Good way to stunt the growth of your cichla. I have pellet trained over 35 cichla and wont say I starved one doing it. Try feeding pellets / sticks everyday pay attention to who eats and who doesnt, do this in three day increments and on the 3rd day feed the cichla who have refused to eat the pellets fresh raw pieces of small cut shrimp & or shiners from a bait shop to assure their getting food. Keep this up and eventually all the cuchla in your tank will associate you dropping food in the tank and the dive / competition for food that bass naturally have will kick in and theyll smack and eat anything that hits the surface of the water in fear if they dont they wont eat.
Basically how I pellet trained all my bass, now some are defiantly harder / stubborn then others and I have had to step out of the norm and handle some differently and baby them into pellets I call it. But never starve, no need too.
