Hi all, i started my 1 gal Thursday. well i got my 1lb live rock, 1.3lb live sand, 1gal saltwater, 1gal ro water all for 10 bucks. my live rock had 1 blue leg crab and 1 crab. it was cool getting hitch hikers. i posted pics on another site of the crab for id and some say its a bad crab some say leave it in. so im going to leave him in there till the tanks cycles or if he eats my blue leg crab. but what would you all do??? this is my first tank so i really insure what to do. but here are a few pics of my tank and of the crab.
