Cross border shopping
 

I have to pick something up from across the border in the next couple days, so was thinking of visiting the Clark Feed & Seed store in Bellingham. Apparently they have quite a selection of fish, incl marine.

Are there any restrictions with bringing back live fish across the border?

No restrictions exist at this time for ornamental fish, just keep your receipt which should be enough to prove it's for ornamental purposes only, you may or may not have to pay duties or taxes.
