hey all ! I have added 50 cardinal tetras to my 85 with 2 12 inch L-114 plecos/ I feed NLS 3 mm to the plecos every other day then 1 mm to the cardinals every 2nd day. My question is I never see the cardinals eat the 1 mm. Does anybody think the 1 mm are small enough?I had this swarm for a week and they all school together and follow the big plecos when they stirr up the gravel but I don't want the cardinals to starve out. The plecos have been in the tank for 4 years now and are in great shape. The swarm of cardinals look very healthy so far.
