Cherry Shrimp ($1.5 each) - medium to small size.
Nice little hardy Cherry Shrimp to sell at $1.5 each. Raising Cherry Shrimp is so easy and also fun as you don't need any bubble/water filter/big tank. A small 2-litre glass jar with live plants and sunlight is good enough to get started. I will give you some duck weed so that your shrimp can enjoy and they can also cling on them and eat the algae.
