Review on Zoo Med Laboratories Banquet Blocks by John Martin

I have purchased these Pleco banquet units a number of times and they have always worked great. I have an adult Pleco that I feed seaweed waffles every night. When I go on vacation for a week I put a block in the tank before heading to the airport and he just loves it. Immediately he comes out of his hiding place and lies down directly on him. When I'm gone for two weeks, I just ask a friend to come over and throw another block in the tank next week. My Pleco always does well with this product and is very healthy. I strongly recommend buying this.
