ok so with my Cichla i dropped 1 feeder in the tank at a time until they tarted hitting them practically the second it hit the water then i would just substitute a rosy red with shrimp or pellets and then gradually kept doing it until it was just pellets and shrimp. BUUT my dats arent that aggressive when eating. anything and everything i drop in the tank goes unnoticed. even feeders they swim around for 5-10 minutes pretty much until the DATS even take notice... they dont seem the mind being starved either.
