I recently picked up a 2 Inch Silver Arowana from my LFS, and asked them if it would be fine to put it into a 29 gallon aquarium with my Black Phantom Tetras, School of Corydoras, and a Senegal Bichir that is only a centimeter longer than the Arowana. They had told me that the fish would be compatible.
After about a week, I couldn't help but notice that small parts of the Arowana's tail fin was missing, and I suspected the tetras and moved them to a different tank. A day later I noticed that the anal fin was nipped. The missing area of the anal fin is around the same size and shape of the bichir's jaw. Is it possible that the bichir took a nip?
