I cannot seem to get these to stick on the side of the glass in the tank so that is why I rated them 4 out of 5. But the fish love them and they will float in the floating plants and the guppies and baby angelfish go after them like they are candy.
These are an awesome food that are a hit with my community tank. They don't stick to the glass that well, but that doesn't matter because my pygmy corydoras and habrosus corys love them. The otocinclus go crazy for them as well. All around an awesome food that I would definitely buy again.
