Oyster-Feast® is a mix of both oyster eggs and ovarian tissue (1-200 microns). Oyster-Feast is naturally size-appropriate for the smallest SPS corals (Acropora & Montipora) up to LPS corals (Goniopora & Favites). Highly suitable feed for a broad range of corals and other invertebrates. Oyster Ovarian Tissue Included Ovarian tissue has all the benefits and nutritional value of the eggs but in a wide range of sizes, down to 1 micron. It is high in both protein and Omega-3 fatty acids. Strong Feeding Response Oyster-Feast elicits a strong feeding response from corals, other invertebrates and fish. Even mysids, amphipods and copepods will feed on Oyster-Feast. Naturally size-appropriate for feeding SPS and LPS corals Highly suitable for a broad range of corals and other invertebrates Fast coral feeding response High in protein and omega-3 fatty acids Stays in suspension Directions 1 - 2 teaspoons per 100 gallon tank per day. Add to a high flow area of the tank, or for target feeding, premix 4 parts tank water with 1 part Oyster-Feast. Because different captive reef systems process nutrients at different rates, we recommend that new users start with half the recommended dose and slowly increase to the full dosage over a 1 month span. When you feed your corals other Reef Nutrition products along with Oyster-Feast, you can take advantage of this strong feeding response by first adding the Oyster-Feast and waiting a few minutes for the polyps to open up to feed before adding the other feeds. Note that color variations in this product are normal. Storage Oyster-Feast should be refrigerated (33-42°F / 1-5°C) before and after opening.
