Happy! Happy! Joy! Joy!
Hey Guys, You won't believe this:
As soon as I got home today, I mixed frozen cyclopeez and Frozen Mysis (as usual). First few attempts, the mandarins ignored (as usual). I thought maybe they will not grab food from the water column, so I squirted the food into the rock work. I did not see the mandarins for a few minutes, they are behind the rock work. Then eventually the male mandarin emerged and I see him pick up a mysis that was caught between a crevice! He even swallowed it! Yep, the male is eating frozen mysis (thawed, obviously). He was probably eating frozen cyclopeez off of the rockwork also, but I cannot confirm this b/c it's really hard to see such small food particals. But mysis is definately accepted the the male mandarin.
The female is still behind the rockwork, hopefully eating. I will update as soon as I confirm that she is eating frozen mysis.
