Unbelievable. The bichir is more interested in swiping at the largest specimens in the tank (the 3+ inch petricolas) and is totally ignoring the small (new) Altos.
If I can somehow pull this stock off, it will be the greatest balancing act in bichir history. I hate that I even had to try this, but it was either 'go for it' or surrender the entire Rift setup forever, blow the biotope, and/or give up specimens (either the existing altos or the bichir).
If by the fish god's graces this actually works, it will say more about the bichir's ability to learn that he need not/can not eat other tankmates and the resiliency of these species as survivors.
