Are 20"+ Bichirs more aggressive?

  • We are currently upgrading MFK. thanks! -neo
When I had my 20"+ bichirs with much smaller bichirs. they showed no signs of aggression. All the bichirs lived in harmony.

Same here, I have 8" grow outs in with 20"+ and no issues. IMO keys are no live food and regular feeding
 
My 21" PBB and 19" Koliba exchange words at times. Same with my 18" Dabola.

I changed my setup around and they are calm. Its only been a week though.

However, my 15" koliba was attacking the PBB when it first was introduced.
