Fish Frenzy® is the base recipe for all LRS food blends. Instead of adding coral specific micro-foods contained in our flagship Reef Frenzy® blend, we add worms and fresh fish eggs. Fish Frenzy® is extremely "clean" as a daily food and is offered in a generous 8 ounce package. Like all LRS blends we peel every shrimp and filet each fish prior to adding to the mixture. These exoskeletons and bones would go uneaten by fish and likely spike nutrient levels in your aquarium in not removed. LRS takes the extra step to remove this waste, while many other aquarium food makers don't.
