i was in a lfs store today and i saw a couple names written on tanks that i didn't recognize. i took pics of the shrimp in the tanks and came home to find out what they really were. they ended up being harlequins and cardinals
cardinal:


harlequin:


they were $6.99 a peice which seems low to me, but im not sure bc ive never seen these guys for sale. should i buy some while theyre there or do you think i could get some for less somewhere else? also, would these two species be ok in the same tank together?
