No luck with shrimp

[Rikko]

The only time I've had bad luck with inverts has been if they are pretty new (days) off a trans shipment. Variety of stresses and quite possibly an inability to purge wastes built up during shipping could certainly be responsible. The best way to buy inverts is also the best way to buy fish.. Like it? Come back and buy it in a week. Sometimes practicality doesn't always allow this, but many stores will be willing to hold one for you if it's a brand new shipment.
