The Golden Pristella Tetra is an excellent fish for the beginner. It is extremely hardy and undemanding and is not at all choosy in its water type. That's probably because it is found naturally in both brackish water as well as soft water. It can even withstand very hard water, though it does do its best in soft. A dark substrate and subdued lighting will show the X-Ray Fish best and enhance its colors. It will not get its full color in hard water or under bright light.
