This is a little bio about them that I have found online from another website:
Nutramar Ova is made from all natural prawn eggs. These eggs are highly nutritious and are an ideal size for feeding corals and smaller fish. Ova makes soft corals, small and large polyp scleractinia (SPS and LPS) go wild, as feeding responses in most species can be seen almost instantly! Ova has also been used to successfully feed Mandarin gobies and pipefish as well as other well known finicky eaters. Ova eggs are packaged with a minimal amount of water making them extremely dense, a little goes a long way in feeding your aquarium. Ingredients: Saltwater prawn eggs, water. We have seen many requests recently for the discontinued Gamma Lobster Eggs from TMC. This food is now called Ova under the Nutramar line of premium foods. Gamma Lobster Eggs and Nutramar Ova are the same food, simply with different packaging and a different name. OVA is an ideal food for anthias, dragonets, pipefish, seahorses, nano-sized gobies, most juvenile fish species, filter-feeding invertebrates and corals! Ova is very rich in protein and natural HUFA's, this nutritious food is a must have when rearing fishes of nearly any species in the larval and post-larval stage.
