Before you purchase this fish you need to make sure you have the proper setup to keep this fish, as it's not easy to keep. It needs a good size tank, at least 6', and lots of swimming room with good water movement. Also you need to be careful with what other tank mates you keep it with, as it can be very aggressive and die from being over stressed. It also has a habit of getting ich. So make sure you can take care of it before you get one.
