Tropic Isle probably has the largest selection of fish and plants, but not a whole lot of variety shrimp-wise, though they may have expanded since I was last there. They are also not T accessible.
Big Fish Little Fish is near Porter square, and much more accessible via public transportation. They have a fairly small quantities and varieties and are a bit pricier. However, I've been impressed with the size of the filter shrimp I've gotten there--much larger than the one's I ordered online. Their dwarf shrimp also have nice color, but they don't usually carry large quantities of them.
The only other LFS I've been to is The Fish Nook in Acton, which is difficult to get to on public transportation, and is not as good as Tropic Isle.
