We have little glowlights tetras that are so tiny still and they can't eat the foods the other fish can eat so we got baby brine for frozen food time at night and we needed flake food for the mornings so I found these to try. The glowlights love them and can eat them easily. They are growing more now that they have food to fit their little mouths. These pellets float and slowly sink over time and are of a pinkish red color that is easily seen in the tank. They are supposed to be balanced nutritional for smaller community fish. A small pinch out of the bag will fill the tank with so many pellets so be careful when feeding. We feed extra because our bigger fish want in on them too so a pinch gets the glowlights plenty and the big fish a snack. We do frozen/freeze dried for optimal color in our tanks but like our flake food to nutritional sound but also enhance colors and this claims to do so also. It's a small bag that is packed full of micro pellets and we paid 4.49 for the bag and it will go a really long way.
