Yesterday when I was ordering a pistol shrimp I stumbled to Blue Zoo Aquatics since they had some tiger pistols for sale and seen that they had some Smithii's as well. I tried to pass it up since I just started SW and now have 3 tanks within a month of the hobby but I just couldnt so I set my 6g tank back up this morning and put my recently acquired Wennerae in that and now have a 12g ready for the Smithii. The Wennerae isnt very active(he stays in the same hole all day long) and is only 1 1/2" so he should be ok in the 5. Ill get some pictures of him while I am acclimating him tomorrow morning.
