I have 5 amano shrimp that I've had for about a year and a half. They are a real asset to the aquarium. Friendly and funny! I keep them in a tank between 76 and 79 degrees. They like healthy water conditions with no ammonia or nitrites, will eat everything from sinking pellets, spirolina wafers, freeze dried blood worms, fresh vegetables (mine like green peppers) and green algae. Mine frequently carry eggs but I have only seen one baby. They also like hiding places for when they moult. If you're not acustomed to them you'll think one died when you see its shell on the bottom of the tank. They moult regularly when they are healthy and growing. My females are about 2 inches long and my males is about 1.5 inches. They are fun to watch...you'll enjoy them.
