There's something wrong with your picture. It's crooked or something. Just kidding but seriously you should be careful with raising shrimp. Some people can do it recreationally and not have a problem but some people find it to be very addictive.
only picture i had after i built it still in the garage will post better non crooked pics after it makes the move into the house...addiction already started thats why i needed three 20L instead of just one
