Green Velvet Shrimp- Neocaridina davidi

They are best kept in a small tank with small tetras and plenty of plants. They will take care of all types of algae quite well, and will also feed on excess food and plant matter that settles along the bottom of the tank. Because shrimp molt, they benefit from the addition of iodine about every month. Without iodine in the water, they are unable to break out of their old "shell". It is recommended that you keep about 1 shrimp per 1/4 gallon of water if possible, and for best algae-eating results.
