Full Answer

The male silvertip tetra has a deeper coppery sheen than the nearly silver female. These midlevel dwellers are peaceful when kept in schools of six or more, but they tend to nip the fins of their tank mates when kept in smaller schools. Adults seldom grow longer than 2 inches. Silvertip tetras are easy to care for and require a minimum tank capacity of 20 gallons. Ideal water conditions for them are a pH level of between 6.8 and 7.5, a water temperature of 72 to 82 degrees Fahrenheit and water hardness to 20 degrees of general hardness (dGH). Adding driftwood to the tank leaches tannins into the water and helps create the ideal water conditions for these fish. Silvertip tetras are omnivores and accept a variety of foods, including flake, frozen, freeze-dried and live foods. Providing a meaty diet conditions them for breeding.
