questions on shrimp tanks

[Lotus]

That is about average price at a LFS.

Online per shrimp is generally cheaper, but shipping has to be done overnight, which adds quite a lot to the cost. To be honest, I never buy fish/shrimp in summer or winter for delivery, simply because the heat/cold could easily kill them, especially if something goes wrong with the delivery. It's generally over 100F here in the summer, and just the thought of them sitting on the hot van all day scares me.
