Same for me Tony. A lot of it floats, no matter how much its soaked. My chromis love it. Some of the larger fish cant even see it and have no idea what the feeding frenzy is about.
I have a lot of baby shrimp fry in my overflow rubble. I fed them some yesterday, {overflows off}. I noticed most of them had one, running around with it. Dont know if they ate it though.
