Hi, I've just bought my first freshwater tank (60x30x30 54 Litre) and have done a pretty good job (Filter, Heater, Sand, Slate structure, Backdrop, Tank ornaments and Plants). I conditioned my water and half filled it with some slate sticking out of the water. I have now introduced two freshwater Blue Crayfish (Ron & Reggie but I can't tell the difference yet). They seem happy enough and spend most of the time in the many hidey holes I've provided. My concerns are feeding. I know they will eat about anything but I have two questions.
1. Other sources tell me to put food in the tank and then take away any they haven't finished in Ten minutes. They never come out to feed so I've tried leaving the food and it disappears overnight. Is this normal?
2. Why should I take the food out after Ten minutes. I'm told that they eat anything including carrion and decaying vegetation so why do I have to remove old food?
Thanks in anticipation of a reply.
