I bought some Ocean Nutrition pellets to feed my fish once my TDO Chroma Boost ran out and once I opened one of the containers today I saw that the pellets are too big for the fish to eat! What do I do now? I tried soaking the food and feeding it but that didn't work. Should I break them up with a mortar and pestle or a blender? Or is there any other solution to this? I cannot return these pellets.
