Nope, that is what I feed them about an hour before lights out. I only feed them like that twice a week, maybe 3 times, and everything is gone come morning. Granted, the MTS might have something to do with it, but I doubt they do that much. If I am not mistaken, there are 9 plecos and 16 loaches in the tank, and they do a number on the food right away. They hide like crazy during the day inside that castle, but when I drop the food in the castle, there is a flurry of action with everybody trying to get some. My Iquitos Tiger pleco is the first to get at it. Then, 2 butterfly plecos, a king tiger pleco, 2 clown plecos, and 2 BN plecos. Okay, that makes 8. It used to be 9 plecos before my L-81 passed away during the catastrophe. I'm trying to get another one, but haven't seen one at the LFS yet.
When the automatic feeder goes off, 5 to 6 angelicus loaches out of the 10 and the 8 hatchet fish almost finish the entire thing off.
