Fish and snails seem to like them. Sink to the bottom quickly.
I feed it to my plecostomus and their fry , blue mystery snails, guppies, neon red crayfish, and cherry shrimp. All love it.
My catfish love these algae wafers so do my guppies.
Fish, shrimp, and snails, oh my... they all love these algae wafers!
I've tried pretty much every algae wafer on the market and have been a fan of Hikari products for years, their algae wafers are one of the few products I feed my breeding trio of Bristlenose Pleco's and their fry.
