I also feed them small snails and have had them in a tank with large snails and they did not kill any of the larger ones.
In other words wether it is fish or dogs, sometimes you can count on them acting the way expect sometimes you can't.
After doing more research on them all I can find that would support my choice of the Bichir is the fact they are less prone to stress from other fish where knifes really like to be able to hide and be left alone unless they want to come out.
I agree..... Bichirs don't hide much at all. Oh, and did I mention that I had 5 Skunks? lol. The more the merrier, lol. They are like tiger barbs, the more you have, the less likely they are to pick on other fish, and pretty much chase each other around, rather than chasing other fish.
Knives just hide too much. They may look cool, but when do you really ever get to watch them, unless you have nowhere for it to hide and increase it's stress levels.
