dose your bichir ever do this?

  • We are currently upgrading MFK. thanks! -neo
Mine do that with each other frequently. I'll have to start watching them around the severum. Bichirs are too cute.
 
Mine does not do that ;)
 
All the time.
I think they're checking if the other fish is a potential mate, or food.

If the bass were a smaller fish, it would be missing its pelvic or anal fin.
