Thank you Willie and Brian! I’m very happy with the fish but they eat very sparingly, they don’t accept pellet food (even presoaked in garlic extract) and the fish/mussel/shrimp frozen mix they eat pretty small quantities. One thing they loved is sterlized freeze dried tubifex cubes. Does tubifex has any protein or fat? I also use vitamins on tubifex and add vits directly to water. I use Brightwell’s Vitamarin-F vitamins and GarlicPower
