Went to an LFS while I was on vacation to Los Angeles to see there brand new 400 gallon shark tank, and I was impressed........until I saw their "sump". Their sump was filled partially with LR and about 3 feet wide, 5 feet long and about 16" deep.......and was inhabited by two 3 to 4 foot black tip reef sharks! These poor sharks had hardly any room to move around and they had a sign in front of them that said "Feed me for 1 dollar". Is there anything that any person can do when they see something like this??
