While these signs should usually be obeyed, sometimes it is legal to ignore them, and in Twin Falls there are a few you may not know you don't have to obey.
On a trip to PetSmart yesterday to get a new goldfish for my son Jack, I was dismayed to find a tank filled with Pacu. I know most of you just went "huh?" Most pet stores bill Pacu as "vegetarian Piranha," but the truth is this little fish can be even deadlier than its Piranha cousin.
Pacu are mainly found in South America, and it was believed that this species were herbivores.
