I use carnivore pellets for my small dats and they eat them fine smallest being about 2 inches.
I have some very small ones and wont try to train them as they are to small but most the time i find that they watch the other dats take the pellet and start eaiting them so i have not had any problems pellet training.
you can get the cichlid gold that sinks look on petsupermarket or vetuk they are some of the lowest prices they also do carnivore and massivore pellets.
yeah they are the same size they only do them in 1 size thats what i feed my small dats then you can step up to the small pack of massivore then go for the bigger bag which the pellet is larger again.
but i use carnivoe and my dats have grown loads since eating them.
