Zoo Med Laboratories AZMBB4 Plankton Banquet Block Feeder Regular

My shrimp went crazy for this stuff. So did all my fish. Lasted exactly a week and everybody was alive when I came back home. In fact, I came home to a bunch of my guppies having given birth and my shrimp eggs hatched. Clearly they were thriving on the stuff. Will buy again!

We have 30 Cichlids in 135 gallon aquarium. Used 4 while we were gone for a week! There was just a tiny bit left. Each time since we have been gone, they swarm our hands when we put them in the tank! Going to be gone for extended period I would recommend this brand!

We went on vacation and added one of these before we left. We came home to living fish. So... it worked!!!

Worked as intended but I came back and the fish tank was disgusting. I usually do weekly water changes (even though the water is visually clean) and I was only gone for 10 days. My fish was fine and healthy but upset and stressed that I had to deep clean her tank.

Fish were alive after a week at the beach. Served it's purpose. I've read about some other products that crumble and fog the water; this did not do that. I would buy again if needed.
