I think Tanked! is a great entertainment tool, but I do agree that many of the aquariums are overstocked. I can't believe how they place sharks in newly established tanks, when these beautiful creatures should only be cared for by experienced aquarists. I also don't agree that they recommend sharks in their top 5 best saltwater fish to have. There are so many needs for keeping sharks, how can they recommended? Sure, they're cool. And I absolutely love sharks. But I have a 180 gallon and will not put even the smallest of cat shark in it.
