Review on Zoo Med Laboratories Banquet Blocks by Katty Berlingo

Unfortunately my plecos (I have 5 different types of L) as well as my whiptails, measles, synodontis and all my other bottom feeders refuse to touch these things. It may be because I treat them to freshly blanched veggies and live food every day or two.However, once added, they remain fully intact for several days.I've tried leaving them whole and breaking them up, but I've never had the fish even taste them Huge disappointment since I bought the 5 pack, spent 2 and now have 3 which are useless to me :(
