I work at PetSmart and a few months ago when the packs first came out, I bought a pack of crypts. So far, so good! Key is to make sure nothing is decomposing in the packs. The gel is easy to rinse off. The Anubias Nana in the middle is also from PetSmart, from the tube packages. I have a piece of Mopani that is soaking that will eventually be in the tank.
