my jar takes anything that hits the buttom, if he cant get it once it hits the water, he will pick them up from the bottom, pellets, shrimp, silversides etc
massivore pellets would be ideal! but they only float very shortly then sink
mine takes cichlid gold, food sticks are too damn small! so i use cichlid gold and he seems to like it
AZOO and Hikari floating pellets. Have tried to start chiclid gold but mine doesnt take the effort of going to bottom to fetch them. My plecos have grown fat on that instead.
