I bought a sample size of the 3 different types (meat, community, and veggie, I think). All my plecos like it, and it disappears in my oddball community tank, too. The smell when you mix it up is horrendous, but after that it is very easy to work with, I cut mine up into small squares and froze it in a plastic bag. When I use it, I take a few cubes out of the bag, and presto. Good luck.
