BTW, I do think this is a good idea. While I used the red light on the frozen, I did not do it the same as I did with the live. I will try a week of shining the light on the live mysids every night. Maybe this will get them trained on the light=food idea. Then I will switch to frozen and see if that is enough of a connection to get them to eat the frozen when it drops in.DWhatley;195195 said:Did you try shining the red light on the frozen? I am curious if the light makes a difference. It would be a nice discovery if it does.
