Silversides stuffed with small NLS some days (They wont eat NLS any other way), other days they get Massivore and Hikari frozen krill. I make sure they have a few days to purge during the week, it makes them hit the food harder when they are hungry.
Do you have dithers in the tank, Mbeatrice? I've got 4 red hook silver dollars, and 2 tin foil barbs...It spreads the aggression so the 4 lents I have, dont turn on each other.
