Circulation Pump Question

[Joshjr619]

I have a 40 gallon tank with clean up crew and two clowns. I haven't purchased a pump yet and I was wondering if I should do so as soon as I have money for it. The other side is I have the money now, but I really wanted to get some sort of shrimp first. Is it a must right away or can I go ahead and buy a shrimp first and get a pump next month?

I would get a pump as flow is vital to a marine tank. Flow and live rock mixed is pretty much a marines filter.

Your basic equipment for the tank (including sources of flow) should be in order before animals are added to it. What do you have providing flow at the moment?
