Hii..
I know these are a rough guide, as some will eat more than others, and different seeds etc, but I don't want to feed too much or they wont trap of fly, but too little will mean they wont fly either, plus, I don't want to under feed them anyway.
Please help.
I didn't find the right solution from the Internet.
