Okay I have 6 bichirs in my main tank and 3 in my grow out tank. Is there any way (without a doubt) that I could add the smaller to the main tank to grow faster. I understand about them needing to grow but also know with the more bichirs you add the less aggression in the tank. Does that count with small ones or are they still looked at as a potential meal. If anybody mixed small and large bichirs successfully could you tell me the way you made it work? It also seems that wild caught a tend to be more of the cannibals (I have a wild delhezi). Any tips or should I just wait for a short period of time (feels like forever)
