8. Iridescent Shark (Pangasianodon hypophthalmus) & Paroon Shark (Pangasius sanitwongsei) – Both of these Monster Catfish are regularly for sale at big box and smaller pet stores (The Paroon is not seen as often anymore), which is ridiculous because neither belongs in an Aquarium. They both come from rivers in Asia such as the Mekong where they can grow into true giants. The Iridescent can reach 4′ and nearly 100lbs, where as the larger Paroon can reach 8′ long and 600lbs! They are both very active swimmers and require plenty of room to roam, so unless you have an Olympic sized swimming pool to spare don’t bother with either of these monsters.

The larger the tank, the less often you will need to tend to it
Aquarium owners who are new to the hobby can often be overwhelmed by the sheer amount of choices in front of them when it comes time to stock a new tank. Often times without doing the proper research, these newbies will often go to one of the larger chain pet stores looking for a new aquatic friend or two, which is when the problems usually begin. Unless that buyer is specifically looking for a certain fish, often times the employees at these pet stores are going to push whatever fish are on "sale" or that they have a "special" on. This is not to say that all of them do this. I have a few personal friends who are adamantly against this, but at the same time they want to keep their jobs and must do what the managers ask of them. Another route is when the new fish owner picks out the type of fish that they like and the employee can give misguided information on just how large the fish may get at full size.
