If you opt for one of these guys make sure you get one that has not been dyed. These are great fish. Some people are offended that they are a hybrid made by man, but I love them. They have amazing personalities and can truly love their owners. They don't like to be kept with more aggressive fish. As long as they know they are the unopposed king of the tank, they are happy to peacefully patrol the tank. They can be kept with smaller schooling fish as well. They shift from one color pattern to the next, eventually ending up a beautiful orange color.
