In the wild, the Gulf Blenny is a grazing fish, that loves to mow down a variety of algae, but they also consume a large number of small invertebrates while doing so. It's important to offer both some greenery and some protein in their diet; this process is made much easier in these aquacultured fish because we can rely in part on the high-quality pellets from Nutramar. The Algae and Color Boost Shots offer them an excellent balanced nutrition for their needs, along with frozen preparations such as Gamma Mysis Shrimp and Gamma Brine Shrimp plus Spirulina will provide proper nutrition.
