our pleco loves these wafers. I drop 3-4 in morning, 3-4 in evening. Our pleco is over 7 inches. Nutritionally balanced and does not disolve easy. This enables the pleco to eat at his liesure instead of the other fish eating it's food. The name of our pleco is Sam (We do not know what sex it is.) love this creature!
These things get swarmed by everything in the tank, not just my frogs, plecos, and corys. They are large, sink fast, and supply a meal for several aquarium inhabitants.
My big common pleco rockets right over to eat these up when I put one in, in the morning. Always had him turn his nose up at ANY other algae wafers and even pellets until I found these. Guess I'll be getting more when I run out of this bag of them.
I have 4 aquariums and non of the fish in any of my tanks incuding the snails and shrimp will eat this. These wafers sit there and rot in my tank, nothing in the aquarium will touch them.
