Great product. My Neocaridina shrimp have all been more active since adding to my shrimp arsenal.
I drop one in my tank. It floated for 3 days then sank to the bottom. Never saw anyone eating it.
These are nicest quality cones I have ever bought for my aquarium. I highly recommend them.
My Red Cherry Shrimp love the new addition of the Casuarina Cones to their tank. I see them feeding off of the cones and they seem to be very happy.
