Spiritofthesoul;5092483; said:A. At that size, the ornate bichir can easily swallow down a 4" FH
B. The ornate spares the FH, but when the FH gets bigger, it would start picking on the ornate
To add to point A. Even if the 7" Ornate doesn't manage to "easily" swallow a 4" fish, it will definitely kill it and may even die if the FH get's stuck in his throat.
I have lost one 6"-7" Endli who killed and tried to eat a 3" Convict (and died in the process) a few weeks back (in a 4ft tank).
I have lost a 7" GT to a 15" Endli in a ~200G tank.
