The wonderful thing about marine fish is they come in all shapes, sizes, and colors. They have unique personalities and needs. Some fish prefer live food and others like to graze on plants or algea. Some fish are very active and never stop swimming while others are content to just lay on the sand for hours. Our likes and dislikes in fish selection is just as unique as our selection of resturaunt when its time to dine out. Everyone is different and thats what makes each aquarium and each hobbiest special.
