My shrimp love these Pops.
I got them for my Opae Ula. After two feedings, I finally see some eat the algae pops during the day with lights on. But after the lights go out at night, they pretty much destroy it. I only put a very small amount as I only have about 60 of them.
Use in both my shrimp and small-fish tanks. They quickly sink and fluff out so they are easily consumed. My "critters" love them.
