One of the prettiest fish in the world, these small tetras have been popular for many years. When properly sourced, transported, and acclimated, this fish is a hardy addition which adds a lot of "pop" to our aquariums. Tetras are one of the most popular aquarium fish because their are just so many kinds that there is something for everyone. Their generally small size and peaceful nature make them easy aquarium inhabitants and many of them are strikingly colorful, making them pleasing to watch. Setup Considerations: The key to keeping almost all the tetras is to keep them in large groups. In nature, they tend to form shoal and/or schools as a defense against predation. In the aquarium, they maintain these instincts and will feel vulnerable if they are not in a group. Luckily, most tetras are small enough that keeping a large group of them is possible even in modest sized aquaria. Most tetras are open-water swimmers and, although they look great in well planted and/or decorated aquariums, they don't require them. Diet: Omnivore In the wild, most tetras are omnivores. During the wet season, they have rich pickings of various insect larvae, micro-crustaceans, worms, etc. In the dry season however, these rich food sources are greatly reduced and many tetras rely on detritus, algae, and biofilm to get them through the lean times. This ability to switch food sources make them very adaptable to aquarium foods and they will relish almost any dry, frozen, or live foods offered.
