A school of these attractive fish will catch the eye of even the most seasoned aquariast. As they get older, the stripe on the Glowlight Tetra becomes more and more pronounced. They just get more and more beautiful. The Glowlight Tetra is a schooling fish and is one of the most peaceful tetras. They are most comfortable in an aquarium with floating plants as well as some open spaces to swim in. Like all fish, they do not over eat, but the Glowlight Tetra does like to eat a small amount of food several times a day. It is best to feed them what they will eat in about three minutes, three or four times a day.
