Hello once again! I was wondering if there are any types of fish that school with danios. They would probably have to be closely related right? My danios are starting to die off, because of reaching their life spans. I have had lots of success with this fish, but I would like to get another specie that does not nip. Are there any others? If so could you please include their temperament? I only have 2 danios now, so I either need more danios or something. Thanks!
