Blue Emperor Tetras (Inpaichthys kerri). More schooling action. Planted Community Aquarium.

Another video but follows closer the schooling action of blue emperor tetras (Inpaichthys kerri) aka royal, purple emperor, or kerri tetras. There are different triggers to get them to school. In this particular scene was the after effect of feeding live Daphnia. Similarly-patterned fish also school with the group when they pass along them, such as the otocinclus and pencilfish. This setup is planted community aquarium. It is a 189L sized tank. Most of the fish are tetras.
