Ogo is a great live food for tangs and other herbivorous fish. It has been proven very useful to us here in house and is used to get fish to eat soon after arrival. This food also gives a constant non-waste producing food source that can be kept in the tank till consumed for all of our herbivorous fish. Ideal for reducing food based aggression.
Ogo purchased in bulk is best kept in a large bucket or barrel with strong aeration and fully submerged. Does best and keeps for longer between 50-65degrees fahrenheit but will still live in temperatures 10 degrees above or below that range.
